[0004] To solve the above technical problem, in a first aspect, the present application provides a detachable water absorption squeegee component, including:

[0005] A mounting plate, with at least one notch formed at its edge;

[0006] A water absorption squeegee; and,

[0007] A disassembly and assembly component corresponding to each notch, the disassembly and assembly component includes a positioning block disposed on the water absorption squeegee and movably snapped into a notch, a pull rod penetrating through the positioning block and extending into the water absorption squeegee, a fixed seat fixedly disposed at one end of the pull rod extending into the water absorption squeegee, a plug pin fixedly disposed at the other end of the pull rod, a handle rotatably disposed on the plug pin, and a spring located between the positioning block and the fixed seat and sleeved on the pull rod. The two ends of the spring are respectively connected to the fixed seat and the positioning block. After the positioning block is snapped into the notch and when the handle rotates to a state perpendicular to the mounting plate, one end of the handle abuts against the surface of the mounting plate.

[0008] In an embodiment of the application, a receiving groove corresponding to a notch is formed on the water absorption squeegee, and a vertical hole communicating with the receiving groove up and down is formed. The positioning block and the fixed seat are respectively fixedly disposed in the receiving groove and the vertical hole; a convex platform protruding relative to the surface of the water absorption squeegee is formed on the surface of the positioning block, and the convex platform can be snapped into the notch; the pull rod penetrates through the positioning block in the receiving groove and extends into the vertical hole to be connected with the fixed seat.

[0014] The detachable squeegee assembly, the mounting plate is mounted on the machine body.

[0015] The beneficial effects of the detachable squeegee assembly and the cleaning robot provided by the present application are as follows: when the squeegee needs to be installed, the portion of the pull rod located between the positioning block and the handle is first placed into the notch, at which time an external force acts on the squeegee, causing the external force to lift the squeegee upward so that the positioning block is snapped into the notch, and then the handle on the latch is rotated, and when the handle is rotated to a state perpendicular to the mounting plate, one end of the handle abuts against the surface of the mounting plate; and at this time, since one end of the spring sleeved on the pull rod pulls the fixing seat fixed in the squeegee, and the other end pulls the positioning block penetrated by the pull rod, the spring force causes the squeegee to have an upward movement tendency relative to the mounting plate, and causes the handle to have another downward movement tendency relative to the mounting plate; at this point, the squeegee and the mounting plate maintain a connected state. When the squeegee on the mounting plate needs to be disassembled, the handle is turned so that the handle is in a horizontal state so as not to press against the mounting plate. External force acts on the squeegee to move the squeegee outward relative to the mounting plate, so as to pull the positioning block on the squeegee out of the notch and move the pull rod out of the notch, thereby realizing the disassembly of the squeegee. Therefore, the squeegee assembly realizes the quick disassembly and installation of the squeegee by means of snap-fit ​​and rotation. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The detachable water suction squeegee assembly and the cleaning robot of the present application will now be specifically described with reference to the accompanying drawings.

[0028] Please refer to Figure 1 , the cleaning robot 200 provided by the embodiment of the present application includes a body 201 and a detachable water suction squeegee assembly 100. Among them, the detachable water suction squeegee assembly 100 includes a mounting plate 10, and the mounting plate 10 is fixedly installed at the bottom of the body 201.

[0029] With reference to Figure 2 and Figure 4 , the water suction squeegee assembly 100 further includes a water suction squeegee 20 and a disassembly and assembly component 30. At least one notch 11 is formed at the edge of the mounting plate 10, and each disassembly and assembly component 30 is correspondingly arranged with a notch 11.

[0030] Among them, the disassembly and assembly component 30 includes a positioning block 31, a pull rod 32, a fixed seat 33, a plug pin 34, a handle 35 and a spring 36. Among them, the positioning block 31 is arranged on the water suction squeegee 20 and is movably buckled in a notch 11, and the pull rod 32 penetrates through the positioning block 31 and extends into the water suction squeegee 20. The fixed seat 33 is fixedly arranged at one end of the pull rod 32 extending into the water suction squeegee 20, the plug pin 34 is fixedly arranged at the other end of the pull rod 32, the handle 35 is rotatably arranged on the plug pin 34, the spring 36 is located between the positioning block 31 and the fixed seat 33 and is sleeved on the pull rod 32, and both ends of the spring 36 are respectively connected to the fixed seat 33 and the positioning block 31. After the positioning block 31 is buckled in the notch 11, when an external force rotates the handle 35 so that the handle 35 rotates to a state perpendicular to the mounting plate 10, one end of the handle 35 abuts against the surface of the mounting plate 10.

[0031] In the above-mentioned water suction scraper assembly 100, the pull rod 32 passes through the positioning block 31. Since the positioning block 31 can be movably clamped in the missing hole 11, the pull rod 32 can freely enter and exit the missing hole 11 at the edge of the mounting plate 10. When installing the water suction scraper 20, first place the part of the pull rod 32 between the positioning block 31 and the handle 35 into the missing hole 11. At this time, an external force acts on the water suction scraper 20, and the external force causes the water suction scraper 20 to lift upward so that the positioning block 31 is buckled in the missing hole 11. Then rotate the handle 35 on the pin 34. When the handle 35 rotates to a state perpendicular to the mounting plate 10, one end of the handle 35 abuts against the surface of the mounting plate 10. And at this time, since one end of the spring 36 sleeved on the pull rod 32 pulls the fixed seat 33 fixedly arranged in the water suction scraper 20, and the other end pulls the positioning block 31 penetrated by the pull rod 32, therefore, the acting force of the spring 36 makes the water suction scraper 20 have an upward movement trend relative to the mounting plate 10, and makes the handle 35 have a downward movement trend relative to the mounting plate 10. At this point, the water suction scraper 20 and the mounting plate 10 maintain a connected state. When disassembling the water suction scraper 20 on the mounting plate 10, rotate the handle 35 so that the handle 35 is in a horizontal state and no longer abuts against the mounting plate 10. An external force acts on the water suction scraper 20 to make the water suction scraper 20 move outward relative to the mounting plate 10, so as to prompt the positioning block 31 on the water suction scraper 20 to be pulled out of the missing hole 11, and the pull rod 32 is removed from the missing hole 11, thus realizing the disassembly of the water suction scraper 20.

[0032] Refer to together Figure 5 , at least one receiving groove 21 and at least one vertical hole 22 are formed in the water suction scraper 20. Among them, each receiving groove 21 is correspondingly arranged with a missing hole 11, and each receiving groove 21 is correspondingly arranged with a vertical hole 22 and is vertically communicated with the receiving groove 21. The positioning block 31 and the fixed seat 33 are respectively fixedly arranged in the receiving groove 21 and the vertical hole 22. A convex platform 311 protruding relative to the surface of the water suction scraper 20 is formed on the surface of the positioning block 31, and the convex platform 311 can be buckled in the missing hole 11. Further, the pull rod 32 passes through the positioning block 31 located in the receiving groove 21 from the convex platform 311 and extends into the vertical hole 22 to be connected with the fixed seat 33, and the fixed seat 33 is connected with the pull rod 32 by a threaded manner.

[0033] As Figure 3 and Figure 4 shown, a groove 351 is formed on one end of the handle 35. One end of the pull rod 32 is placed in the groove 351 and the pin 34 passes through the handle 35 and the pull rod 32. Among them, one end of the pull rod 32 is placed in the groove 351 through which the pin 34 passes. After the pin 34 passes through the pull rod 32, both ends of the pin 34 are rotatably connected with the handle 35.

[0034] Refer to in combination Figure 2 and Figure 6, the mounting plate 10 includes a bottom plate 12 and at least one connecting piece 13 fixedly arranged at the edge of the bottom plate 12. The bottom plate 12 is provided with a first accommodation hole 121 at the position where the connecting piece 13 is arranged. Each connecting piece 13 is provided with a U-shaped second accommodation hole 122 at its edge. The first accommodation hole 121 and the second accommodation hole 122 communicate vertically to form a missing hole 11. Moreover, the straight section 122 and the circular section 123 of the first accommodation hole 121 communicate horizontally with each other. The straight section 122 of the first accommodation hole 121 communicates vertically with the opening of the U-shaped second accommodation hole 122; the convex platform 311 is a circular structure matching the circular section 123. Among them, for the mounting plate 10, the vertical communication direction and the horizontal communication direction are perpendicular to each other, and the vertical communication direction is parallel to the direction from the bottom plate to the connecting plate.

[0035] Furthermore, two disassembly and assembly components 30 can be arranged on the water suction squeegee 20. Two missing holes 11 are also opened on the mounting plate 10. The water suction squeegee 20 is detachably connected to the two missing holes 11 of the mounting plate 10 through the two disassembly and assembly components 30 in one-to-one correspondence. The water suction squeegee assembly 100 is installed on the body 201 of the cleaning robot 200. The two disassembly and assembly components 30 are symmetrically distributed along the central axis of the water suction squeegee 20. In this way, the connection force points between the water suction squeegee 20 and the mounting plate 10 can be balanced, and the water suction squeegee 20 can also be more stable when working in contact with the ground. The central axis is the axis of symmetry along the walking direction of the cleaning robot 200.

[0036] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
