Wherein, the water absorption rake 2 is positioned behind the brush disc 3 along the walking direction of the floor washing machine. That is, the brush plate 3 is provided at the front end of the bottom of the body 1, and the wiper 2 is provided at the rear end of the bottom of the body 1. The water absorption scratcher 2 is used for contacting with the ground to generate a sealed space, and recycling sewage scraped from the ground by the adhesive tape. The sewage tank is connected with the water absorption scratchers 2 through sewage absorption pipes and is used for recycling sewage collected by the water absorption scratchers 2 into the sewage tank through negative pressure.

In order to achieve the basic functions of the floor washing machine, the floor washing machine of the embodiment of the present invention may further include other necessary modules or components, such as a power system, a scrubbing system, a suction and drainage system, a control system, and the like. It should be noted that any suitable existing configuration may be used for other necessary modules or components included in the scrubber machine. In order to clearly and briefly explain the technical solutions provided by the present invention, the above parts will not be described again, and the drawings in the specification are also simplified correspondingly. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended.

In the present embodiment, the traveling module 4 includes one or more sets of universal wheels 401 having a 360-degree rotation function. By means of the structural design, the flexible steering and the transverse movement of the floor washing machine can be realized, the floor washing machine can realize turning in a small range, corners and small-area ground can be flexibly scrubbed, the ground with heavy stains is cleaned in a reciprocating mopping mode, and the ground cleaning efficiency is greatly improved.

In order to avoid interference between the structures, the walking module 4 is arranged between the water absorption rake 2 and the brush disc 3. Moreover, the number of the universal wheels 401 is even, and every two universal wheels 401 form a rotating power wheel set. Two universal wheels 401 contained in each rotating power wheel set are arranged at two sides of the bottom of the machine body 1 along the walking direction perpendicular to the working time of the floor washing machine. The number of the rotating power wheel sets is multiple, and the rotating power wheel sets are arranged at intervals along the walking direction of the floor cleaning machine during working.

In this way, the universal wheels 401 can provide even support to the scrubber, which can better balance the scrubber. In an alternative embodiment, the steerable wheel 401 does not have active steering functionality. The floor washing machine at this time may be a hand-push type floor washing machine, and the user pushes the floor washing machine forward by hand. Of course, in another alternative embodiment, the universal wheels 401 also have an active steering function, and are driven by a driving unit, such as a motor, to become powered wheels. The scrubber at this time may be an autopilot scrubber.

Further, a first lifting mechanism 5 can be arranged between the machine body 1 and the water absorption rake 2, and the water absorption rake 2 can be switched between a first working position and a first lifting position under the driving of the first lifting mechanism 5. When in the first working position, the water absorption scratcher 2 descends to contact with the ground. When the water absorption rake is at the first lifting position, the water absorption rake 2 is lifted and separated from the ground. In an alternative embodiment, the first lifting mechanism 5 may comprise a first telescopic assembly and a first connecting member 6 connected between the first telescopic assembly and the suction rake 2. The first telescopic assembly is any one of an electric telescopic rod, a pneumatic cylinder and a hydraulic cylinder and comprises a first cylinder barrel and a first piston rod which is telescopic in the telescopic first cylinder barrel. The first cylinder barrel is fixed on the machine body 1, the first piston rod extends downwards and is connected with the upper end of the first connecting piece 6, and the lower end of the first connecting piece 6 is connected with the water absorption rake 2. In this embodiment, the first connecting member 6 may specifically be a rod body, and two ends of the rod body are respectively movably connected with the lower end of the first piston rod and the upper end of the water absorption rake 2, and may specifically be hinged.

Similarly, a second lifting mechanism 7 can be arranged between the machine body 1 and the brush disc 3, and the brush disc 3 can be switched between a second working position and a second lifting position under the driving of the second lifting mechanism 7. When in the second operating position, the brush plate 3 is lowered into contact with the ground. When in the second raised position, the brush plate 3 is raised away from the floor. In an alternative embodiment, the second lifting mechanism 7 may comprise a second telescopic assembly and a second coupling 8 connected between the second telescopic assembly and the brush disc 3. The second telescopic group is any one of an electric telescopic rod, a pneumatic cylinder and a hydraulic cylinder and comprises a second cylinder barrel and a second piston rod which is telescopic in the telescopic second cylinder barrel. The second cylinder is fixed on the machine body 1, the second piston rod extends downwards and is connected with the upper end of the second connecting piece 8, and the lower end of the second connecting piece 8 is connected with the brush disc 3. In this embodiment, the second connecting member 8 may be a rod body, and two ends of the rod body are respectively movably connected with the lower end of the second piston rod and the upper end of the brush disc 3, and may be hinged.

Further, the traveling module 4 has a working mode in which it carries the scrubber machine in a linear direction, and a steering mode in which it carries the scrubber machine in a curved direction. When the walking module 4 is in the working mode, the water absorption rake 2 is in the first working position, and the brush disc 3 is in the second working position. When the walking module 4 is in the steering mode, the water absorption rake 2 is in the first lifting position, and the brush disc 3 is in the second lifting position.

Through the structural design, when the universal wheel 401 turns, the brush disc 3 and the water absorption rake 2 are lifted to be separated from the contact with the ground, so that the running resistance of the floor washing machine can be reduced, and the steering of the floor washing machine is quickly realized. After the floor-washing machine moves to the right position, the brush disc 3 and the water absorption rake 2 are lowered to be in contact with the ground, and cleaning is started.

In order to realize the automatic lifting and descending of the brush plate 3 and the water absorption rake 2, a control module (not shown) connected with the walking module 4, the first lifting mechanism 5 and the second lifting mechanism 7 can be arranged on the machine body 1, and the control module can control the walking module 4, the first lifting mechanism 5 and the second lifting mechanism 7 to operate according to the above mode. Namely: when the universal wheel 401 turns, the first lifting mechanism 5 and the second lifting mechanism 7 are controlled to operate, the water absorption rake 2 and the brush disc 3 are lifted, and the floor cleaning machine can quickly turn. After the floor cleaning machine moves to the right position, the first lifting mechanism 5 and the second lifting mechanism 7 are controlled to operate, the water absorption rake 2 and the brush disc 3 are lowered to be in contact with the ground, and then the floor cleaning machine can start cleaning operation.

In this embodiment, the control module may be implemented in any suitable manner. Specifically, for example, the control module may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the microprocessor or processor, Logic gates, switches, an Application Specific Integrated Circuit (ASIC), a Programmable Logic Controller (PLC), and an embedded micro-Controller Unit (MCU), examples of which include, but are not limited to, the following: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F 320. It will also be appreciated by a person skilled in the art that instead of implementing the functionality of the control module in the form of pure computer readable program code, it is entirely possible to logically program the method steps such that the control unit implements the same functionality in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded micro control units, etc.

It should be noted that, in the description of the present invention, the terms "first", "second", and the like are used for descriptive purposes only and for distinguishing similar objects, and no order is shown between the two, and no indication or suggestion of relative importance is understood. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.

Any numerical value recited herein includes all values from the lower value to the upper value that are incremented by one unit, provided that there is a separation of at least two units between any lower value and any higher value. For example, if it is stated that the number of a component or a value of a process variable (e.g., temperature, pressure, time, etc.) is from 1 to 90, preferably from 21 to 80, and more preferably from 30 to 70, it is intended that equivalents such as 15 to 85, 22 to 68, 43 to 51, 30 to 32 are also expressly enumerated in this specification. For values less than 1, one unit is suitably considered to be 0.0001, 0.001, 0.01, 0.1. These are only examples of what is intended to be explicitly recited, and all possible combinations of numerical values between the lowest value and the highest value that are explicitly recited in the specification in a similar manner are to be considered.

Unless otherwise indicated, all ranges include the endpoints and all numbers between the endpoints. The use of "about" or "approximately" with a range applies to both endpoints of the range. Thus, "about 20 to about 30" is intended to cover "about 20 to about 30", including at least the endpoints specified.

It is to be understood that the above description is intended to be illustrative, and not restrictive. Many embodiments and many applications other than the examples provided would be apparent to those of skill in the art upon reading the above description. The scope of the present teachings should, therefore, be determined not with reference to the above description, but should instead be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. The disclosures of all articles and references, including patent applications and publications, are hereby incorporated by reference for all purposes. The omission in the foregoing claims of any aspect of the subject matter that is disclosed herein is not intended to forego such subject matter, nor should the applicants be construed as having contemplated such subject matter as being part of the disclosed subject matter.
