Description

Technical Field

[0001] The utility model belongs to the field of floor-sweeping robots, and particularly relates to a mopping mechanism for a floor-sweeping robot. Background Technique

[0002] As an intelligent cleaning tool, the floor-sweeping robot is very popular among young people nowadays; at present, the floor-sweeping robots on the market can not only complete cleaning work along the edge, centralized cleaning, random cleaning, straight-line cleaning and other paths, but also control the rotation of the mop cloth, mop the floor while sweeping, strengthen the cleaning effect, and achieve an anthropomorphic home cleaning effect.

[0003] The mopping mechanism of the floor-sweeping robot generally includes a motor, a speed-changing component, a telescopic component and a mopping component. The speed-changing component is used to output different rotation speeds. The telescopic component is connected to the mopping component to make the up-and-down position of the mopping component adjustable. When the mopping component enters an uneven area, it can ensure that the mop cloth on the mopping component is always in contact with the ground; however, in the mopping component of the traditional floor-sweeping robot, the mop cloth is directly fixed to the mop cloth fixing seat by a pressing plate. Due to the size limitation of the pressing plate, it can only press and fix the edge position of the central hole of the mop cloth. The peripheral part of the mop cloth is prone to wrinkle and deform during mopping and cleaning. Especially when the side of the mop cloth encounters raised objects such as carpets and floor mats, the edge part of the mop cloth is prone to turn over, thus affecting the subsequent normal mopping and cleaning operation; in addition, after the floor-sweeping robot returns to the base station to clean the mop cloth, it is necessary to rotate the mop cloth at a high speed to drain the water. If the peripheral part of the mop cloth is not effectively fixed, it is difficult for the mop cloth to return to a natural flat state after being drained. When mopping the floor next time, due to the dry deformation of the mop cloth edge and insufficient wetting time of the mop cloth, the contact surface with the ground is more likely to wrinkle, affecting the mopping effect. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems raised in the above background technique, and provide a

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A mopping mechanism for a floor sweeping robot, comprising a double-headed motor. Two driving ends of the double-headed motor are respectively connected to a speed-changing assembly. The speed-changing assembly is connected to a mopping assembly through a telescopic assembly. It is characterized in that the mopping assembly includes a mounting seat fixedly connected to the bottom of the telescopic assembly. A mop fixing seat is arranged below the mounting seat. A plurality of drainage holes and a plurality of clamping plate holes are arranged on both the mounting seat and the mop fixing seat. Two semi-circular clamping plates are arranged in the clamping plate holes. A circular groove is arranged on the bottom surface of the mop fixing seat. A sliding hole communicating with the clamping plate hole is arranged on the side wall of the circular groove. A sliding rod is arranged in the sliding hole. One end of the sliding rod is fixedly connected to one of the clamping plates, and the other clamping plate is fixedly connected to the side wall of the clamping plate hole. A bowl-shaped member is arranged in the circular groove. The bowl-shaped member is connected to the mop fixing seat and the mounting seat through screws. A mop is fixed below the mop fixing seat through the bowl-shaped member.

[0007] Further, the mounting seat is provided with openings corresponding to the drainage holes and the clamping plate holes, and the openings are annularly distributed.

[0008] Further, protrusions are arranged on the mop, and the protrusions are arranged between the two clamping plates and clamped tightly by them.

[0009] Further, an enlarged hole step is arranged on one side of the sliding hole close to the clamping plate hole, and a spring is connected to the enlarged hole step. The other end of the spring abuts against the corresponding clamping plate.

[0010] Further, an inclined surface matching the outer wall of the bowl-shaped member is arranged at one end of the sliding rod close to the circular groove.

[0011] Further, the thickness of the bowl-shaped member is less than the thickness of the mop.

[0012] Compared with the existing technology, the advantages of this mopping mechanism for a floor sweeping robot are as follows:

[0013] 1. By arranging protrusions on the mop, when the two clamping plates are closed, it is easier to fix the whole mop, avoiding the mop from deforming during mopping and cleaning and drying operations, and affecting the mopping and cleaning effects.

[0014] 2. By arranging a circular groove on the mop fixing seat, the mop can be pressed and fixed on the mop fixing seat in cooperation with the bowl-shaped member, and the disassembly is convenient.

[0020] The following embodiments are only for illustrative purposes and are not intended to limit the scope of the present utility model.

[0021] Referring to Figures 1 to 3 , a mopping mechanism for a floor-sweeping robot includes a double-headed motor 1. Two driving ends of the double-headed motor 1 are respectively connected to a speed-changing component 2. The speed-changing component 2 is connected to a mopping component 4 through a telescopic component 3. The above double-headed motor 1, speed-changing component 2, and telescopic component 3 are all composed of the same structures as those in the prior art. The mopping component includes a mounting seat 401 fixedly connected to the bottom of the telescopic component 3. A mop fixing seat 402 is provided on the lower side of the mounting seat 401. A plurality of drain holes 403 and a plurality of clamp plate holes 404 are provided on both the mounting seat 401 and the mop fixing seat 402. The mounting seat 401 is provided with openings corresponding to the drain holes 403 and the clamp plate holes 404, and the openings are annularly distributed. Among them, when washing the mop 411, the water in the mop 411 is squeezed out through the drain holes 403 above the mounting seat 401, which accelerates the drainage speed and effect of the mop 411 compared with the traditional method of only squeezing water from the periphery and bottom of the mop 411;

[0022] Two semi-circular clamp plates 405 are arranged in the clamp plate holes 404. A circular groove 406 is provided on the bottom surface of the mop fixing seat 402. A slide hole 407 communicating with the clamp plate holes 404 is provided on the side wall of the circular groove 406. A slide bar 408 is arranged in the slide hole 407. One end of the slide bar 408 is fixedly connected to one of the clamp plates 405, and the other clamp plate 405 is fixedly connected to the side wall of the clamp plate hole 404. An enlarged hole step is provided on one side of the slide hole 407 close to the clamp plate hole 404. The enlarged hole step is connected to a spring 413, and the other end of the spring 413 abuts against the corresponding clamp plate 405.

[0023] A bowl-shaped part 409 is arranged inside the circular groove 406. The bowl-shaped part 409 is connected to the mop fixing seat 402 and the mounting seat 401 through screws 410. A mop 411 is fixed below the mop fixing seat 402 through the bowl-shaped part 409. It should be noted that the thickness of the bowl-shaped part 409 is less than the thickness of the mop 411 to avoid wear caused by the contact between the bowl-shaped part 409 and the ground when the mop contacts the ground.

[0024] Protrusions 412 are arranged on the mop 411. The protrusions 412 are arranged between two clamping plates 405 and clamped and fixed by them. By arranging the protrusions 412, it is easier to fix the mop 411 when the two clamping plates 405 are closed, and avoid the deformation of the mop during mopping and cleaning and drying operations, which affects the mopping and cleaning effects.

[0025] One end of the sliding rod 408 close to the circular groove 406 is provided with an inclined surface matching the outer wall of the bowl-shaped part 409. One side of the sliding hole 407 close to the clamping plate hole 404 is provided with an enlarged hole step. The enlarged hole step is connected with a spring 413. The other end of the spring 413 abuts against the corresponding clamping plate 405.

[0026] When the mop 411 needs to be replaced in the present utility model, the fixing of the mop 411, the mop fixing seat 402, the mounting seat 401 and the bowl-shaped part 409 can be released by removing the screws 410. Take out a new mop 411, align its central hole with the circular groove 406, then place the protrusions 412 on the mop 411 into the corresponding clamping plate holes 404, and then place one end of the bowl-shaped part 409 into the circular groove 406. The mop 411 and the mop fixing seat 402 are pressed tightly through the arc-shaped outer wall of the bowl-shaped part 409. When the bowl-shaped part 409 abuts against one end of the sliding rod 408, push the other end of the sliding rod 408 to move into the clamping plate hole 404, thereby clamping and fixing the protrusions 412 on the mop 411. Finally, reinstall the screws 410.

[0027] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
