[0033] The front blade 30, the rear blade 40 and the bottom plate 20 are installed as a whole on the bracket 10, and the front blade 30 is clamped between the first surface of the bottom plate 20 and the first baffle plate 11 of the bracket 10.

[0034] In some embodiments, the bracket 10 and the bottom plate 20 are detachably connected with each other, which can quickly realize the disassembly and assembly between the bracket 10 and the bottom plate 20.

[0035] In some embodiments, the bracket 10 and the bottom plate 20 are connected by nuts.

[0036] In some embodiments, one end of the second baffle plate 12 is provided with a limiting component 13, and the first end 51 of the pressure strip 50 abuts against the limiting component 13. The first end 51 of the pressure strip 50 is attached to one end of the rear blade 40 through the limiting component 13, and the second end 52 of the pressure strip 50 is attached to the other end of the rear blade 40 through the locking assembly 60, thereby fixing the rear blade 40, the bottom plate 20 and the front blade 30 as a whole between the first baffle plate 11 and the second baffle plate 12.

[0037] Still referring to FIGS. 1 and 2, the squeegee further includes a fixing base 70. The fixing base 70 is arranged on the second baffle plate 12, and the locking assembly 60 is installed on the fixing base 70.

[0040] In some embodiments, the second end 52 of the pressure strip 50 has a triangular bending structure, and the abutting portion 61 is perpendicular to one plane of the triangular bending structure, which can achieve maximum compression.

[0041] In some embodiments, by pushing or pulling the push-pull portion, the abutting portion 61 can be moved so that the abutting portion 61 tightly abuts against the pressure strip 50 or leaves from the pressure strip 50 so as to achieve the compression or relaxation between the abutting portion 61 and the pressure strip 50 without the need for additional work to operate the locking assembly 60. The operation is simple and convenient, which can improve the efficiency of disassembly and replacement of the pressure strip, and improve the working efficiency of the floor cleaning machine.

[0042] Still referring to FIGS. 2 and 3, in some embodiments, the push-pull portion includes a handle 62 and a rod portion 63. The handle 62 is arranged on one end of the rod portion 63, and the abutting portion 61 is arranged on the other end of the rod portion 63. The rod portion 63 passes through the fixing base 70, and the handle 62 and the abutting portion 61 are respectively arranged on two opposite sides of the fixing base 70.

[0043] In some embodiments, the handle 62 and the rod portion 63 have a T-shape, and the handle 62 can facilitate the user to pull the rod portion 63.

[0044] In some embodiments, the abutting portion 61 is a screw, and the rod portion 63 has a hollow structure. A screw rod of the abutting portion 61 may be connected to the rod portion 63 through insertion or interference fit.

[0045] In other embodiments, the abutting portion 61 and the rod portion 63 may also be connected by a thread connection. An external thread is provided on an outer surface of the screw rod of the abutting portion 61 , and an internal thread engaging with the external thread is provided on an inner surface of the rod portion 63.

[0046] In some embodiments, the locking assembly 60 further includes a gasket 64. The gasket 64 is sleeved on an outer periphery of the screw rod of the abutting portion61 . The gasket 64 can tighten the connection between the abutting portion 61 and the rod portion 63, which can prevent the abutting portion 61 from coming out of the rod portion 63 when pulling the push-pull portion.

[0047] In some embodiments, the locking assembly 60 further includes an elastic portion 65 arranged between the fixing base 70 and the abutting portion 61 . The elastic portion 65 has a first compression state, and when the elastic portion 65 is in the first compression state, an elastic force of the elastic portion 65 is configured to press the abutting portion 61 and the second end 52 of the pressure strip 50.

[0048] In some embodiments, the elastic portion 65 is located between the gasket 64 and the fixing base 70. The elastic portion 65 in the first compression state has an elastic force along an axial direction of the elastic portion, which acts on the fixing base 70 and the gasket 64 respectively. The fixing base 70 is fixedly arranged on the second baffle plate 12. The elastic force can tightly press the abutting portion 61 against the pressure strip 50 to achieve the compression of the pressure strip 50 and the rear blade 40.

[0049] In some embodiments, the elastic portion 65 is sleeved on a periphery of the rod portion 63, and the rod portion 63 is pulled in a direction from the abutting portion 61 to the fixing base 70, so that the elastic portion 65 has a second compression state, A compression amount of the elastic portion 65 in the second compression state is greater than the compression amount of the elastic portion 65 in the first compression state.

[0050] In some embodiments, as the elastic portion 65 is sleeved on the periphery of the rod portion 63 and located between the fixing base 70 and the gasket 64, when the rod portion 63 is pulled outward, the gasket 64 and the abutting portion 61 move in the same direction as the rod portion 63 to further compress the elastic portion 65 so that the elastic portion 65 is in the second compression state. At this time, the abutting portion 61 moves away from the pressure strip 50 to release the pressure strip 50 and the rear blade 40, which allows for disassembly and replacement of the front blade 30and the rear blade 40. After replacement, the rod portion 63 is pushed in the direction from the abutting portion 61 to the fixing base 70. When the abutting portion 61 abuts against the pressure strip 50 again, the elastic portion 65 returns to the first compression state to complete the compression of the pressure strip 50 and the rear blade 40.

[0051] In some embodiments, the elastic portion 65 is a spring. The spring has good compression and elastic release effect, which can facilitate the compression and relaxation between the abutting portion 61 and the pressure strip 50.

[0052] In some embodiments, the locking assembly 60 further includes a positioning component 66 installed on the fixing base 70, and the rod portion 63 passes through the positioning component 66 and the fixing base 70 simultaneously.

[0053] Specifically, the positioning component 66 and the handle 62 are arranged on the same side of the fixing base 70.

[0054] In some embodiments, the positioning component 66 is provided with a first groove 67, and the first groove 67 passes through the positioning component 66 in a radial direction of the positioning component 66. The rod portion 63 is provided with a positioning protrusion 68, and the first groove 67 is configured to place the positioning protrusion 68.

[0055] In some embodiments, the positioning protrusion 68 is symmetrically arranged on the rod portion 63.

[0056] In some embodiments, when pulling the rod portion 63 to separate the abutting portion 61 from the pressure strip 50, the elastic portion 65 is in the second compression state. If the user does not apply a tensile force to the rod portion 63 against the elastic force of the elastic portion 65, the elastic portion 65 will rebound under the action of the elastic force, and the abutting portion 61 will abut against the pressure strip 50 again, which is not conducive to the disassembly and assembly of the front and rear blades. Therefore, by providing the first groove 67 on the positioning- io -component 66, when the elastic portion 65 is in the second compression state, the positioning protrusion 68 is placed in the first groove 67, and the first groove 67 can restrict the movement of the rod portion 63, which can prevent the elastic portion 65 from rebounding, and facilitate the disassembly and replacement of the front and rear blades by the user.

[0057] In some embodiments, the positioning component 66 has a whole cylindrical structure. The positioning component 66 is further provided with a second groove 69. The second groove 69 passes through the positioning component 66 in the radial direction of the positioning component 66, and an extension direction of the second groove 69 has an angle with an extension direction of the first groove 67. A depth of the second groove 69 is greater than a depth of the first groove 67.

[0058] In some embodiments, the second groove 69 is configured to allow the positioning protrusion 68 to pass through when pulling or pushing the rod portion 63 so as not to block the movement of the rod portion 63.

[0059] In some embodiment, the depth of the second groove 69 can be determined according to actual usage conditions while ensuring complete contact between the abutting portion 61 and the pressure strip 50.

[0060] In some embodiments, the extension direction of the second groove 69 is perpendicular to the extension direction of the first groove 67. After pulling the rod portion 63 along the second groove 69 and turning the rod portion 63 by 90 degrees to align the positioning protrusion 68 with the first groove 67, the positioning protrusion 68 is limited in the first groove 67.

[0061] FIG. 4 is a schematic enlarged structural view of a locking assembly according to another embodiment of the present disclosure.

[0062] It should be noted that the difference between this embodiment and the above embodiment lies in specific structure of the locking assembly. For the content not specifically described in this embodiment, reference can be made to the above- n -embodiment and will not be repeated here.

[0063] Referring to FIG. 4, the fixing base 70 includes a first fixing plate 71 and a second fixing plate 72. The first fixing plate 71 and the second fixing plate 72 are perpendicular to each other.

[0064] In some embodiments, the abutting portion 61 passes through the second fixing plate 72 and abuts against the second end 52 of the pressure strip 50.

[0065] In some embodiments, the push-pull portion includes a first connecting component 81 and a second connecting component 84. The first connecting component 81 has a movable end 82 and a fixed end 83. The fixed end 83 is rotatably connected with the fixing base 70.

When the fixed end 83, the movable end 82 and the abutting portion 61 are aligned in a line, a compressed state is formed.

[0066] In some embodiments, the fixed end 83 is rotatably connected with the first fixing plate 71 .

[0067] In some embodiments, two ends of the abutting portion 61 are respectively located on two opposite sides of the second fixing plate 72. One end of the abutting portion 61 is rotatably connected with the second connecting component 84, and the other end abuts against the pressure strip 50.

[0068] In some embodiments, when the first connecting component 81 is pulled in a direction away from the second end 52 of the pressure strip 50, the first connecting component 81 rotates around a connecting hole between the fixed end 83 and the first fixing plate 71 to change the position of the movable end 82 and then drive the second connecting component 84 to move in the direction away from the second end 52 of the pressure strip 50 so as to drive the abutting portion 61 away from the pressure strip 50 to achieve the relaxation between the abutting portion 61 and the pressure strip 50.When the abutting portion 61 and the pressure strip 50 need to be compressed again, the first connecting component 81 is pushed in a direction close to the second end 52 of the pressure strip 50 until the fixed end 83, the movable end 82 and the abutting portion 61 are aligned so as to achieve the compression between the butting portion 61 and the pressure strip 50.
