In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0038] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0039] The present embodiment proposes a cleaning device, which may be a sweeper, a floor scrubber, etc., which is not specifically limited here. The cleaning device includes a squeegee mechanism, an adsorption mechanism, a sewage tank, etc. When the cleaning device is working, the squeegee mechanism moves on the ground in a specified direction (i.e., the walking direction), and a sealed space is formed between the pressure strip in the squeegee mechanism and the ground. The adsorption mechanism sucks out the sewage in the enclosed space and discharges it into the sewage tank to complete the cleaning of the ground. The adsorption mechanism of the present embodiment is a fan, which is connected to the sealed space of the squeegee mechanism through a pipeline. In other embodiments, the adsorption mechanism can also be other suction devices, as long as it can suck out the sewage in the enclosed space, which is not specifically limited here.

[0040] The existing cleaning equipment has only one water absorption chamber, and the cleaning effect is not good, especially when cleaning the blind path 100. Since the surface of the blind path 100 has a raised portion 10 (structures such as strip-shaped raised portions and circular bosses), the blind path 100 has an undulating surface, resulting in poor water absorption effect of the fan. After being cleaned by the floor scrubber, a lot of sewage still remains on the blind path 100, and the cleaning effect is not good.

[0041] To solve the above problems, Figure 1 to Figure 3 As shown, this embodiment also proposes a squeegee mechanism, which includes a support frame 1, and the upper end of the support frame 1 has a water suction port 2, which can be connected to the adsorption mechanism. Figure 1The first pressure strip 3, the second pressure strip 4 and the third pressure strip 5 are arranged from front to back in sequence (in the direction indicated by the middle arrow), the first pressure strip 3, at least part of the lower end surface of the support frame 1 and the second pressure strip 4 are arranged to form a first water absorption cavity, the second pressure strip 4, at least part of the lower end surface of the support frame 1 and the third pressure strip 5 are arranged to form a second water absorption cavity, and the first water absorption cavity and the second water absorption cavity are both connected to the water absorption port 2. When cleaning the ground, the adsorption mechanism sucks out the sewage in the first water absorption cavity and the second water absorption cavity respectively through the water absorption port, and cleans the ground in sequence through the two water absorption cavities, thereby improving the cleaning quality of the ground, especially the blind path 100.

[0042] In the present embodiment, the squeegee mechanism has a good cleaning effect on the blind path 100. Taking the cleaning of the blind path 100 as an example, the specific structure of the squeegee mechanism is described in detail.

[0043] like Figure 1 to Figure 3 As shown, the support frame 1 includes an end plate 11 and three clamping parts 12, and the upper end of the end plate 11 has a water suction port 2. The three clamping parts 12 are arranged at intervals at the lower end of the end plate 11 along the walking direction, and the first pressure strip 3, the second pressure strip 4 and the third pressure strip 5 are respectively arranged on the corresponding clamping parts 12. Specifically, the clamping part 12 is provided with a mounting groove, and the upper end of each pressure strip is clamped in the mounting groove of the corresponding clamping part 12 to improve the installation stability of the three pressure strips.

[0044] Furthermore, if Figure 2 and Figure 6 As shown, the end plate 11 is provided with two guide cavities 13 at intervals along the walking direction, and the cross-sectional area of ​​the guide cavity 13 gradually decreases from bottom to top along the height direction. The top ends of the two guide cavities 13 are both connected to 2, and the bottom ends of the two guide cavities 13 are respectively connected to the first water absorption cavity and the second water absorption cavity, so that the sewage in the first water absorption cavity and the second water absorption cavity is sucked into the water suction port 2 through the respective connected guide cavities 13. Setting the guide cavity 13 in a flat trumpet shape can play a role in guiding sewage, which is conducive to improving the water absorption efficiency and cleaning effect.

[0045] It should be noted that the support frame 1 of the squeegee has a straight section and a curved section, and both ends of the straight section extend outward with a curved section so that the squeegee roughly presents a horn structure, and the length of the straight section is much greater than the length of the curved section, so as to maximize the volume of the first water absorption chamber and the second water absorption chamber, thereby improving the water absorption effect.

[0046] Furthermore, the lower end opening of the guide cavity 13 is a waist-shaped opening, and both ends of the waist-shaped opening extend to both ends of the straight line segment along the length direction of the support frame 1 to increase the opening area of ​​the lower end of the guide cavity 13, thereby further improving the water absorption effect.

[0047] In this embodiment, the end plate 11 and the three clamping parts 12 are arranged in equal length and are integrally formed. The clamping parts 12 are strip-shaped fin structures. The three clamping parts 12 are bent inwardly toward the walking direction at both ends in the length direction to form a bending angle, and the bending angles of the three clamping parts 12 gradually increase from front to back along the walking direction. Figure 3 As shown, the middle part of the three pressure strips is a long straight line segment, and the two ends of the straight line segment are symmetrical arc segments. The straight line segments of the three pressure strips can extend into the raised parts 10 of the blind path 100 for cleaning, further improving the cleaning effect. In addition, as Figure 4 As shown, since the first strip 3, the second strip 4 and the third strip 5 are respectively formed along their respective clamping portions 12, the bending angles of the ends of the first strip 3, the second strip 4 and the third strip 5 gradually increase, so that the ends of the same side of the three strips are closely attached to each other to ensure the sealing of the first water absorption cavity and the second water absorption cavity.

[0048] like Figure 1 to Figure 3 As shown, the lower end of the first bead 3 is provided with a plurality of partition grooves 30 spaced apart along its length direction, and a retaining edge 31 is formed between adjacent partition grooves 30. Water outside the first bead 3 enters the first water absorption chamber through the plurality of partition grooves 30. The plurality of partition grooves 30 separate the lower end of the first bead 3 into a plurality of retaining edges 31, and some retaining edges 31 are individually turned into the first water absorption chamber under the squeezing action of the protrusion 10, while the remaining retaining edges 31 not subjected to the squeezing action remain in a vertical state to improve the sealing effect of the first water absorption chamber. At the same time, compared with setting the edge of the lower end of the bead as an integral structure, each retaining edge 31 of the first bead 3 of this embodiment has better flexibility, which is conducive to each retaining edge 31 individually fitting on the undulating surface of the blind path 100 to adaptively turn and deform, which is conducive to improving the sealing of the first water absorption chamber. In other embodiments, a water inlet hole can also be provided through the lower end of the first bead 3, and the first water absorption chamber is connected to the external environment through the water inlet hole, so that the water outside the first bead 3 enters the first water absorption chamber through the water inlet hole.

[0049] Furthermore, in the vertical direction, the lower end of the second bead 4 is lower than the lower end of the first bead 3 and the lower end of the third bead 5, and the lower end of the second bead 4 can abut against the ground, that is, the surface of the blind path 100. Figure 2 Specifically, the lower end of the second pressure strip 4 is flush with the bottom end of the roller group 7 in the Figure 2 The bottom end of the roller 72 of the roller assembly 7 is flush to ensure that when the squeegee mechanism cleans the blind path 100 (or the horizontal ground), the roller 72 is supported on the surface of the blind path 100, and the lower end of the second pressure strip 4 is in contact with the surface of the blind path 100, and the lower end of the first pressure strip 3 and the lower end of the scraper portion 52 are both in contact with the surface of the blind path 100 to improve the sealing performance of the first water absorption chamber and the second water absorption chamber.

[0050] Furthermore, the thickness of the second pressure strip 4 is smaller than the thickness of the first pressure strip 3 and the thickness of the wiper portion 52, so that the second pressure strip 4 has better flexibility, which is convenient for flipping into the second water absorption cavity under the squeezing action of the raised portion 10 of the blind path 100, so that part of the water in the first water absorption cavity enters the second water absorption cavity through the gap between the raised portions 10.

[0051] like Figure 3 and Figure 5 As shown, the third pressure strip 5 also includes a water removal portion 51 and a water wiping portion 52. The water removal portion 51 is provided on the inner side of the water wiping portion 52 facing the second pressure strip 4. The water wiping portion 52 is used to ensure the sealing effect of the second water absorption chamber. The water wiping portion 52 of this embodiment is a rubber strip, and the water removal portion 51 is a brush strip. A plurality of bristles are planted to form the water removal portion 51 on the inner side of the water wiping portion 52. The water removal portion 51 and the water wiping portion 52 are arranged to be equal in length, and each bristle of the water removal portion 51 can be bent and deformed independently, so that the water removal portion 51 can be deformed to fit the surface contour of the blind path 100 to sweep out the water marks remaining on the edge of the raised portion 10. Of course, the water removal portion 51 can also have a brush strip with a water absorption function, such as a cloth strip, etc. The cloth strip can not only sweep out the water marks remaining on the edge of the raised portion 10, but also remove the water marks remaining on the edge of the raised portion 10 by adsorption, thereby further improving the cleaning quality.

[0052] It should be noted that, in one embodiment, the third pressure strip 5 only includes the water removal portion 51. When the brushes in the water removal portion 51 have a sufficient number and thickness, the second water absorption chamber can be ensured to have good sealing. In another embodiment, the third pressure strip 5 only includes the wiper portion 52. When the wiper portion 52 has sufficient flexibility, the wiper portion 52 can also conform to the surface contour of the blind path 100 to achieve deformation, so as to clean the water marks remaining on the edge of the raised portion 10.

[0053] When cleaning the blind tract 100, the ribs 31 of the first pressure strip 3 are turned inward under the squeezing action of the raised portion 10 of the blind tract 100, and the other ribs 31 that have not been turned over are conducive to ensuring the sealing of the first water absorption chamber. The fan sucks out part of the sewage in the first water absorption chamber through the suction port 2, and the other part of the sewage flows into the second water absorption chamber through the gap of the raised portion 10 of the blind tract 100. The water removal portion 51 fits the surface contour of the blind tract 100 to achieve ups and downs deformation, so as to sweep out the water marks remaining on the edge of the raised portion 10, which is convenient for suction from the second water absorption chamber, avoiding excessive water marks remaining on the blind tract 100, and improving the cleaning effect of the blind tract 100.

[0054] like Figure 1 and Figure 3As shown, the squeegee mechanism also includes a walking assembly, which includes a support beam 6 and two roller groups 7. The support beam 6 is arranged at the upper end of the support frame 1 and extends to the front and rear sides of the support frame 1 along the walking direction. A roller group 7 is respectively arranged at both ends of the support beam 6 along the walking direction, and the roller group 7 is supported by rolling on the ground, that is, the surface of the blind path 100. The two roller groups 7 are respectively located at the front and rear sides of the support frame 1 along the walking direction, so that the support frame 1 is subjected to a uniform support force along the walking direction, thereby realizing the smooth walking of the squeegee mechanism.

[0055] Furthermore, the walking assembly is provided with at least two groups, and the support beams 6 of at least two groups of walking assemblies are arranged at intervals along the length direction of the support frame 1, so that the support frame 1 is subjected to a uniform support force along its length direction, further improving the stability of the squeegee mechanism during walking. The walking assembly of this embodiment has two groups, and the two support beams 6 are respectively located at the two ends of the length direction of the support frame 1, and the four roller groups 7 are jointly supported on the surface of the blind path 100, so as to achieve the smooth walking of the squeegee mechanism. Of course, in other embodiments, the walking assembly can also be arranged in three groups, four groups or five groups or more, which is not specifically limited here.

[0056] like Figure 1 and Figure 3 As shown, the end plate 11 is provided with first holes 111 at both ends along the length direction thereof, and the support beam 6 is provided with second holes 61. The walking assembly further includes bolts 8, which are sequentially inserted into the first holes 111 and the second holes 61 to lock the support beam 6 on the end plate 11. The first hole 111 is provided with limited convex strips 112 on both sides along the length direction of the end plate 11, and the support beam 6 is clamped in the two limited convex strips 112, so that the support beam 6 is installed on the end plate 11 along the walking direction, thereby improving the installation accuracy of the support beam 6.

[0057] Furthermore, the roller assembly 7 includes an adapter frame 71 and a roller 72, the roller 72 is rotatably mounted on the adapter frame 71, and the adapter frame 71 is adjustable in height direction at one end of the support beam 6 along the walking direction. The walking assembly also includes a locking nut 9, and the support beam 6 is provided with a second hole 61 at both ends along its length direction (i.e., the walking direction), and a screw is provided at the top of the adapter frame 71. After the screw passes through the second hole 61, it is threadedly matched with the locking nut 9, so that the adapter frame 71 is threadedly connected to the support beam 6, so as to quickly adjust the height of the adapter frame 71, thereby adjusting the distance between the three pressure strips and the ground.

[0058] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments.
