Detailed Implementation

[0047] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0048] The following is for reference. Figures 1-9 The cleaning head 100 according to an embodiment of the present invention allows users to easily assemble and disassemble the scraper 21 without replacing the entire structure of the cleaning head 100. It should be noted that this application uses the cleaning head 100 in a floor scrubber as an example, but it is not limited thereto.

[0049] Reference Figures 1-9As shown, the cleaning head 100 according to a first aspect embodiment of the present invention includes a housing 1 and a scraper assembly 2. The housing 1 forms the main external structural outline of the cleaning head 100 and protects the internal structures; the scraper assembly 2 is mounted on the housing 1 and is used to scrape away dirt.

[0050] Specifically, the scraper assembly 2 includes a scraper 21 and a scraper support frame 22. The scraper 21 is used to scrape off dirt from the surface to be cleaned, and the scraper support frame 22 is connected to the scraper 21. The scraper 21 is detachably mounted on the housing 1.

[0051] Specifically, the scraper 21 generates friction through contact with the surface to be cleaned. As the scraper 21 moves along the surface to be cleaned, it removes dirt (such as dust, water stains, etc.) from the surface. The scraper support frame 22 can support the scraper 21, improve the support strength of the scraper 21, and reduce the risk of deformation of the scraper 21.

[0052] In this embodiment, the scraper 21 is detachably connected to the housing 1. Compared to fixing the scraper and the housing into a non-detachable integral structure, the embodiment in this case allows users to easily disassemble and replace the scraper 21 separately without replacing the entire structure of the cleaning head 100, thereby reducing the cost of replacing the scraper 21.

[0053] Therefore, by setting up the cleaning head 100, users can easily disassemble and replace the scraper 21, avoiding the need to replace the entire structure of the cleaning head 100, thereby improving the ease of disassembly and assembly of the scraper assembly 2, reducing costs, and ensuring the water-wiping effect of the scraper 21.

[0054] According to some optional embodiments of the present invention, refer to Figure 4 and Figure 5 As shown, the housing 1 is provided with a mounting groove 11 extending in the left and right direction; the scraper assembly 2 also includes a fixing member 23, which is installed in the mounting groove 11. The fixing member 23 is provided with a first sliding groove 231, and the bottom of the fixing member 23 is provided with a first opening 232 communicating with the first sliding groove 231. The top of the scraper 21 passes through the first sliding groove 231 and the first opening 232.

[0055] The top of the scraper 21 can fit into the first groove 231 of the fixing member 23, and the rest of the scraper 21 can extend through the first opening 232 at the bottom of the fixing member 23 toward the surface to be cleaned. This allows the fixing member 23 to fit into the first groove 231 and avoids interference with the structural extension path of the scraper 21 toward the surface to be cleaned, thereby improving the design rationality of the fixing member 23.

[0056] In addition, the fastener 23 is installed in the mounting groove 11 of the housing 1, and the top of the scraper 21 is fitted in the first sliding groove 231 of the fastener 23. This allows the scraper 21 to be indirectly connected to the housing 1. Moreover, since the fastener 23 protects the scraper 21, it can reduce the wear of the scraper 21 and thus improve its practicality.

[0057] Specifically, refer to Figures 1-5 As shown, one end of the housing 1 is provided with a first snap-fit ​​part 12, and the scraper assembly 2 also includes a snap-fit ​​member 24. The snap-fit ​​member 24 is provided at one end of the fixing member 23, and the snap-fit ​​member 24 is provided with a second snap-fit ​​part 241. The first snap-fit ​​part 12 and the second snap-fit ​​part 241 are snap-fitted together.

[0058] It is understood that the housing 1 has a first snap-fit ​​part 12 at one end in the left-right direction, and the snap-fit ​​part 24 is connected to one end in the left-right direction of the fixing part 23. The second snap-fit ​​part 241 on the snap-fit ​​part 24 engages with the first snap-fit ​​part 12 on the housing 1 in the left-right direction. This allows the snap-fit ​​part 24 to have a limiting effect in the left-right direction of the housing 1. The snap-fit ​​part 24 can further limit the displacement of the fixing part 23 in the left-right direction of the housing 1, thereby ensuring the positional stability of the fixing part 23 and preventing the fixing part 23 from falling off the housing 1.

[0059] Furthermore, referring to Figure 3 As shown, a relief groove 13 is formed at one end of the housing 1. The first snap-fit ​​part 12 is located on one side of the relief groove 13. The snap-fit ​​part 24 is disposed in the relief groove 13. Moreover, the snap-fit ​​part 24 does not protrude from the end face of one end of the housing 1 in the left and right direction. This arrangement can reduce the overall width of the cleaning head 100 in its left and right direction, avoid the risk of interference with the outside world caused by the snap-fit ​​part 24 extending beyond the edge of the housing 1 in the left and right direction. It can also make the relief groove 13 play a certain role in structural protection of the snap-fit ​​part 24, thereby improving the structural compactness of the cleaning head 100 and the rationality of the arrangement of the snap-fit ​​part 24.

[0060] Specifically, the first snap-fit ​​part 12 is configured as a snap-fit ​​groove opening towards the relief groove 13, and the second snap-fit ​​part 241 is configured as a snap-fit ​​connector protruding towards the snap-fit ​​groove. This arrangement facilitates the snap-fit ​​connector to be smoothly snapped into the snap-fit ​​groove. Moreover, compared with other connection methods (such as screw connection, adhesive connection, etc.), the snap-fit ​​connection does not require additional parts to connect the snap-fit ​​groove and the snap-fit ​​connector into a whole, avoiding unnecessary material consumption. It can also provide sufficient holding force to ensure that the snap-fit ​​connector will not loosen or fall off during the use of the scraper assembly 2.

[0061] Moreover, the snap-fit ​​connection structure is simple, reliable, and has quick and convenient disassembly and installation functions, which can effectively reduce the time and cost required for the maintenance and replacement of snap-fit ​​components.

[0062] Furthermore, referring to Figures 1-5 As shown, the snap-fit ​​member 24 has an insertion hole 242, one end of the fixing member 23 is inserted into the insertion hole 242, and the top of the scraper 21 is provided with a clearance notch 211 to avoid the snap-fit ​​member 24.

[0063] Understandably, along the left-right direction, one end of the fastener 23 is inserted into the socket 242 on the snap-fit ​​member 24, thus connecting the two into a whole, ensuring their relative installation position and preventing the fastener 23 from moving undesirably. Since the snap-fit ​​member 24 is located on one side of the upper end of the scraper 21, a clearance notch 211 is provided on the scraper 21 to avoid the snap-fit ​​member 24. This avoids the risk of structural interference and collision between the snap-fit ​​member 24 and the scraper 21, thereby improving the rationality of the spatial arrangement.

[0064] Specifically, refer to Figure 8 As shown, the mounting groove 11 is provided with one of a limiting groove and a limiting rib, and the fastener 23 is provided with the other of a limiting groove and a limiting rib. The limiting groove and the limiting rib are engaged in a limiting fit in the left and right directions.

[0065] For example, the mounting groove 11 is provided with a limiting rib, and the fastener 23 is provided with a limiting groove. The limiting rib and the limiting groove limit each other in the left and right directions, so that the housing 1 can limit the fastener 23 in the left and right directions, thereby ensuring the positional stability of the fastener 23 and preventing the fastener 23 from falling off the housing 1.

[0066] Furthermore, referring to Figure 8 As shown, a limit block 214 is provided at one end of the scraper 21, and the limit block 214 is engaged with one end of the fixing member 23 in the left and right directions.

[0067] In other words, along the left and right direction of the housing 1, the limiting block 214 at one end of the scraper 21 is matched with the limiting block 214 at one end of the fixing member 23. This allows the fixing member 23 to limit the scraper 21 in the left and right direction, thereby ensuring the positional stability of the scraper 21 and preventing the scraper 21 from falling off the fixing member 23.

[0068] Specifically, one end of the mounting groove 11 is provided with a mounting port 111, the fastener 23 is installed in the mounting groove 11 through the mounting port 111, and the scraper 21 passes through the groove of the mounting groove 11.

[0069] Understandably, referring to Figure 4As shown, the mounting groove 11 has a mounting port 111 at one end in the left-right direction. The fixing member 23 can be inserted into the mounting groove 11 through the mounting port 111 in the left-right direction. The scraper 21 is inserted into the first sliding groove 231 of the fixing member 23 in the left-right direction. The scraper 21 passes through the first opening 232 of the fixing member 23 and the groove of the mounting groove 11 on the side facing the surface to be cleaned. This can avoid interference and obstruction of the structural extension path of the scraper 21 to the side of the surface to be cleaned, thereby improving the rationality of the design.

[0070] Alternatively, the fastener 23 can be a metal part. Since metal has high structural strength, this arrangement can improve the structural reliability and service life of the fastener 23.

[0071] According to some optional embodiments of the present invention, refer to Figure 4 As shown, the housing 1 is provided with a mounting groove 11 extending in the left and right direction. One end of the mounting groove 11 is provided with a mounting opening 111. The top of the scraper 21 is detachably mounted to the mounting groove 11 through the mounting opening 111, and the top of the scraper 21 passes through the groove of the mounting groove 11.

[0072] Specifically, the mounting groove 11 has a mounting opening 111 at one end in the left-right direction. The top of the scraper 21 can be selectively inserted into the mounting groove 11 through the mounting opening 111, thereby achieving the effect of detachably mounting the scraper 21 onto the housing 1. Furthermore, the scraper 21 has a slot in the mounting groove 11 on the side facing the surface to be cleaned. This can avoid the housing 1 interfering with or blocking the structural extension path of the scraper 21 towards the surface to be cleaned, thereby improving the rationality of the design.

[0073] According to some optional embodiments of the present invention, refer to Figure 9 As shown, the housing 1 is provided with a first magnetic attractor 14, and the scraper assembly 2 further includes a second magnetic attractor 25. The top of the scraper 21 is disposed on the second magnetic attractor 25, and the scraper 21 is detachably disposed on the housing 1 by the magnetic attraction between the first magnetic attractor 14 and the second magnetic attractor 25. For example, the first magnetic attractor 14 can be a magnetic component, and the second magnetic attractor 25 can be an iron block, etc., and is not limited thereto.

[0074] The top of the scraper 21 is connected to the second magnetic member 25. The second magnetic member 25 can magnetically attract the first magnetic member 14 on the housing 1. At this time, the scraper 21 is connected as a whole by the magnetic attraction between the first magnetic member 14 and the second magnetic member 25. When it is necessary to remove the scraper 21 from the housing 1, the scraper 21 can overcome the magnetic attraction between the first magnetic member 14 and the second magnetic member 25 under the action of external force, so as to successfully remove the scraper 21 from the housing 1.

[0075] Specifically, refer to Figure 9As shown, the housing 1 is provided with a mounting groove 11 extending in the left and right direction. The first magnetic suction member 14 is disposed in the mounting groove 11, and the second magnetic suction member 25 is installed in the mounting groove 11. This arrangement allows the first magnetic suction member 14 to make full use of the space in the mounting groove 11, improving the rationality of the space arrangement. Moreover, the mounting groove 11 can also provide structural protection for the first magnetic suction member 14. When the scraper 21 is installed in the housing 1, the second magnetic suction member 25 is also installed in the mounting groove 11. This can prevent external objects from interfering with or colliding with the second magnetic suction member 25, thereby ensuring the installation stability of the scraper 21 and thus ensuring the stability of the wiping effect.

[0076] Furthermore, the second magnetic suction member 25 is provided with a second sliding groove, and the bottom of the second magnetic suction member 25 is provided with a second opening communicating with the second sliding groove. The top of the scraper 21 passes through the second sliding groove and the second opening.

[0077] The top of the scraper 21 can fit into the second groove of the second magnetic member 25, and the top of the scraper 21 can also extend through the second opening at the bottom of the second magnetic member 25 toward the surface to be cleaned. This allows the scraper 21 to fit into the second groove, and also avoids the housing 1 from interfering with or blocking the structural extension path of the scraper 21 toward the surface to be cleaned, thereby improving the design rationality of the fixing member 23.

[0078] In addition, the second magnetic suction member 25 is installed in the mounting groove 11 of the housing 1, and the top of the scraper 21 is fitted into the second sliding groove of the second magnetic suction member 25. This allows the scraper 21 to be indirectly connected to the housing 1. Moreover, since the second magnetic suction member 25 protects the scraper 21, it can reduce the wear of the scraper 21 and thus improve its practicality.

[0079] According to some optional embodiments of the present invention, refer to Figure 2 As shown, the scraper 21 is provided with a through hole 212, and the scraper support frame 22 includes a scraper cover plate 222 and a scraper bracket 221. The scraper cover plate 222 is provided on the front side of the scraper 21, and the scraper bracket 221 is provided on the rear side of the scraper 21. One of the scraper cover plate 222 and the scraper bracket 221 is connected to the other of the scraper cover plate 222 and the scraper bracket 221 after passing through the through hole 212.

[0080] Along the thickness direction of the scraper 21, the scraper cover plate 222 and the scraper bracket 221 are respectively connected to both sides of the scraper 21. The scraper 21 is provided with through mounting holes. The scraper cover plate 222 is connected to the scraper bracket 221 after passing through the mounting holes of the scraper 21. In this way, the scraper cover plate 222, the scraper 21 and the scraper bracket 221 can be connected into a whole. The scraper cover plate 222 and the scraper bracket 221 can respectively strengthen the structural strength of the local area of ​​the scraper 21 on both sides of the thickness direction of the scraper 21. That is, without affecting the flexibility of the scraper 21, the scraper cover plate 222 and the scraper bracket 221 improve the deformation resistance of the scraper 21, reduce the risk of the scraper 21 being easily deformed under external force, and ensure the effectiveness of the scraper 21 in removing stains during cleaning.

[0081] According to some optional embodiments of the present invention, refer to Figure 1 As shown, elastic support blocks 213 are provided at both ends of the front side of the scraper 21 in the left and right directions. The elastic support blocks 213 are suitable for supporting the cleaning surface.

[0082] Specifically, along the left and right direction, elastic support blocks 213 are provided at both ends of the front side of the scraper 21. The elastic support blocks 213 will undergo elastic deformation after being subjected to external force, which can provide elastic support for the scraper 21. They can also absorb and dissipate some energy during the deformation process, reducing the vibration and impact transmitted from the elastic support blocks 213 to the scraper 21, thereby improving the rationality of the arrangement.

[0083] When the cleaning equipment moves forward, the elastic support block 213 arranged on the front of the scraper 21 allows the scraper 21 to have a certain gap from the ground (at this time, the scraper 21 is in a backward flipped state), and dirt can enter the roller brush and suction port through the gap; when the cleaning equipment moves backward, the scraper 21 forms an interference area with the ground through the downward pressure of part of the structure of the housing 1 (such as the transparent window of the roller brush) (at this time, the scraper 21 is in a forward flipped state), thereby achieving the effect of scraping away water stains. In the above way, the cleaning effect of the floor brush can be effectively improved and the water stains on the surface to be cleaned can be reduced.

[0084] Reference Figures 1-5 As shown, the cleaning head 100 according to the second aspect embodiment of the present utility model includes a housing 1 and a scraper assembly 2. One end of the housing 1 is provided with a first snap-fit ​​portion 12. The scraper assembly 2 is used to scrape off dirt on the surface to be cleaned. The scraper assembly 2 is provided with a second snap-fit ​​portion 241. The scraper assembly 2 is detachably disposed on the housing 1 through the snap-fit ​​cooperation between the first snap-fit ​​portion 12 and the second snap-fit ​​portion 241.

[0085] Specifically, the first snap-fit ​​part 12 on the housing 1 and the second snap-fit ​​part 241 on the scraper assembly 2 snap-fit ​​together, so that the scraper assembly 2 and the housing 1 can be connected as a whole. This also facilitates the quick assembly and disassembly of the scraper assembly 2 on the housing 1. Moreover, the snap-fit ​​connection has a high connection strength, which can improve the installation stability of the scraper assembly 2, thereby improving the ease of assembly and disassembly and the reliability of the connection of the scraper assembly 2.

[0086] According to some optional embodiments of the present invention, refer to Figures 1-5 As shown, the scraper assembly 2 includes a fixing member 23, a scraper 21, and a snap-fit ​​member 24. The fixing member 23 is installed on the housing 1. A first groove 231 is provided inside the fixing member 23. A first opening 232 communicating with the first groove 231 is provided at the bottom of the fixing member 23. The scraper 21 is used to scrape off dirt from the surface to be cleaned. The top of the scraper 21 passes through the first groove 231 and the first opening 232. The snap-fit ​​member 24 is provided at one end of the fixing member 23. The snap-fit ​​member 24 is provided with a second snap-fit ​​part 241.

[0087] The top of the scraper 21 can fit into the first groove 231 of the fixing member 23, and the top of the scraper 21 can also extend through the first opening 232 at the bottom of the fixing member 23 toward the surface to be cleaned. This allows the fixing member 23 to fit into the first groove 231 while avoiding interference with the normal cleaning operation of the scraper 21, thereby improving the design rationality of the fixing member 23. The fixing member 23 is installed in the mounting groove 11 of the housing 1, and the top of the scraper 21 fits into the first groove 231 of the fixing member 23. This allows the scraper 21 to be indirectly connected to the housing 1. Moreover, since the fixing member 23 protects the scraper 21, it can reduce the wear of the scraper 21, thereby improving its practicality.

[0088] In addition, the housing 1 has a first snap-fit ​​part 12 at one end in the left-right direction, and the snap-fit ​​member 24 is connected to one end in the left-right direction of the fixing member 23. The second snap-fit ​​part 241 on the snap-fit ​​member 24 and the first snap-fit ​​part 12 on the housing 1 snap-fit ​​together in the left-right direction of the housing 1. This allows the snap-fit ​​member 24 to have a limiting effect in the left-right direction of the housing 1. The snap-fit ​​member 24 can further limit the displacement of the fixing member 23 in the left-right direction of the housing 1, thereby ensuring the positional stability of the fixing member 23 and preventing the fixing member 23 from falling off the housing 1.

[0089] Specifically, refer to Figures 1-5 As shown, a relief groove 13 is formed at one end of the housing 1, a first snap-fit ​​part 12 is located on one side of the relief groove 13, a snap-fit ​​part 24 is disposed in the relief groove 13, and the snap-fit ​​part 24 does not protrude from the end face of one end of the housing 1.

[0090] The above arrangement can reduce the overall width of the cleaning head 100 in the left and right directions, avoid the risk of interference with the outside world caused by the snap-fit ​​24 extending beyond the edge of the housing 1 in the left and right directions, and also allow the clearance groove 13 to provide structural protection for the snap-fit ​​24 to a certain extent, thereby improving the structural compactness of the cleaning head 100 and the rationality of the arrangement of the snap-fit ​​24.

[0091] Reference Figure 6 and Figure 7 As shown, the cleaning head 100 according to the third aspect embodiment of the present utility model includes a housing 1 and a scraper 21. The housing 1 is provided with a mounting groove 11 extending in the left-right direction. One end of the mounting groove 11 is provided with a mounting opening 111. The scraper 21 is used to scrape off dirt from the surface to be cleaned. The scraper 21 is an integrally formed structural component. The top of the scraper 21 is detachably mounted to the mounting groove 11 from the mounting opening 111 and passes through the groove of the mounting groove 11.

[0092] Specifically, the mounting groove 11 has a mounting port 111 at one end in the left-right direction. The fixing member 23 can be inserted into the mounting groove 11 through the mounting port 111. The scraper 21 is inserted into the first sliding groove 231 of the fixing member 23 in the left-right direction. The scraper 21 passes through the first opening 232 of the fixing member 23 and the groove of the mounting groove 11 on the side facing the surface to be cleaned. This can avoid interference and obstruction of the structural extension path of the scraper 21 to the side of the surface to be cleaned, thereby improving the rationality of the design.

[0093] Reference Figure 9 As shown, the cleaning head 100 according to the fourth aspect embodiment of the present invention includes a housing 1 and a scraper assembly 2. The housing 1 is provided with a first magnetic suction member 14. The scraper assembly 2 includes a scraper 21 and a second magnetic suction member 25. The scraper 21 is used to scrape off dirt from the surface to be cleaned. The top of the scraper 21 is disposed on the second magnetic suction member 25. The scraper 21 is detachably disposed on the housing 1 by magnetic attraction between the first magnetic suction member 14 and the second magnetic suction member 25.

[0094] For example, the first magnetic suction component 14 can be a magnet, the second magnetic suction component 25 can be an iron block, and the top of the scraper 21 is connected to the magnet. The magnet can generate a magnetic attraction effect with the iron block on the housing 1. At this time, the scraper 21 is connected as a whole by the magnetic attraction between the magnet and the iron block. When it is necessary to remove the scraper 21 from the housing 1, the scraper 21 can overcome the magnetic attraction between the magnet and the iron block under the action of external force, so as to successfully remove the scraper 21 from the housing 1.

[0095] According to some optional embodiments of the present invention, refer to Figure 9 As shown, the housing 1 is provided with a mounting groove 11 extending in the left-right direction, the first magnetic member 14 is disposed in the mounting groove 11, and the second magnetic member 25 is installed in the mounting groove 11.

[0096] The above arrangement allows the first magnetic suction member 14 to make full use of the space in the mounting groove 11, improving the rationality of the spatial arrangement. Moreover, the mounting groove 11 can also provide structural protection for the first magnetic suction member 14. When the scraper strip 21 is installed in the housing 1, the second magnetic suction member 25 is also installed in the mounting groove 11. This can prevent external objects from interfering with or colliding with the second magnetic suction member 25, thereby ensuring the installation stability of the scraper strip 21 and thus ensuring the stability of the wiping effect.

[0097] Reference Figure 8 As shown, the cleaning head 100 according to the fifth aspect embodiment of the present utility model includes a housing 1 and a scraper assembly 2. The housing 1 is provided with a mounting groove 11 extending in the left-right direction. The scraper assembly 2 includes a scraper 21 and a fixing member 23. The scraper 21 is used to scrape off dirt on the surface to be cleaned. The fixing member 23 is installed in the mounting groove 11. The fixing member 23 is provided with a first sliding groove 231. The bottom of the fixing member 23 is provided with a first opening 232 communicating with the first sliding groove 231. The top of the scraper 21 passes through the first sliding groove 231 and the first opening 232.

[0098] The top of the scraper 21 can fit into the first groove 231 of the fixing member 23, and the rest of the scraper 21 can extend through the first opening 232 at the bottom of the fixing member 23 toward the surface to be cleaned. This allows the fixing member 23 to fit into the first groove 231 and avoids interfering with the normal cleaning work of the scraper 21, thereby improving the design rationality of the fixing member 23.

[0099] In addition, the fastener 23 is installed in the mounting groove 11 of the housing 1, and the top of the scraper 21 is fitted in the first sliding groove 231 of the fastener 23. This allows the scraper 21 to be indirectly connected to the housing 1. Moreover, since the fastener 23 protects the scraper 21, it can reduce the wear of the scraper 21 and thus improve its practicality.

[0100] According to some optional embodiments of the present invention, the mounting groove 11 is provided with one of a limiting groove and a limiting rib, and the fixing member 23 is provided with the other of a limiting groove and a limiting rib, and the limiting groove and the limiting rib are engaged in a limiting fit in the left and right directions.

[0101] For example, the mounting groove 11 is provided with a limiting rib, and the fastener 23 is provided with a limiting groove. The limiting rib and the limiting groove limit each other in the left and right directions, so that the housing 1 can limit the fastener 23 in the left and right directions, thereby ensuring the positional stability of the fastener 23 and preventing the fastener 23 from falling off the housing 1.

[0102] Alternatively, refer to Figure 8As shown, a limit block 214 is provided at one end of the scraper 21, and the limit block 214 is engaged with one end of the fixing member 23 in the left and right directions.

[0103] In other words, along the left and right direction of the housing 1, the limiting block 214 at one end of the scraper 21 is matched with the limiting block 214 at one end of the fixing member 23. This allows the fixing member 23 to limit the scraper 21 in the left and right direction, thereby ensuring the positional stability of the scraper 21 and preventing the scraper 21 from falling off the fixing member 23.

[0104] The cleaning device according to the sixth aspect of this utility model includes the cleaning head 100 of the above embodiment. The cleaning device having the cleaning head 100 can facilitate the user to disassemble and replace the scraper 21, thereby improving the practicality and economy of the scraper assembly 2 and thus enhancing the market competitiveness of the cleaning device.
