[0035] Specific embodiment

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below, in conjunction with the accompanying figures accompanying the embodiments of the present invention. It is understood that the described embodiments represent only a portion of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other achievements obtained by a person with ordinary skill in art, without creative work, fall within the scope of protection of the present invention.

[0037] Furthermore, the present invention may repeat reference numerals and / or letters in various examples, such repetition being for the sake of simplicity and clarity and not in itself an indication of a relationship between the various embodiments and / or parameters discussed. In addition, the present invention provides examples of various specific processes and materials, but a person with ordinary skill in the art can carry out the application of other processes and / or the use of other materials.

[0038] With reference to Figures 1 and 2, a first aspect of the present invention provides a cleaning device 100 comprising: a housing 10, a mop element 20, a transmission assembly 40, and main brushes 30. The main brushes 30 are a plurality of brushes, which are rotationally coupled to the housing 10. The transmission assembly 40 is connected to the housing 10. The mop element 20 is fitted to the transmission assembly 40 and spaced from the main brushes 30, and the mop element 20 is rotatable under the action of the transmission assembly 40.

[0039] The mop element 20 can be ring-shaped.

[0040] The cleaning device 100 can be a floor washer, a sweeper, a floor cleaning machine, etc. and examples of embodiments of this invention are not limited to this.

[0041] As the main brushes 30 are a plurality of brushes which are rotatably connected to the housing 10, the plurality of main brushes 30 has a better effect for removing dust and waste from the floor compared to a single main brush 30, and the cleaning of hair (human hair, animal hair) is more complete, and the cleaning effect is good.And as the transmission assembly 40 is connected to the housing 10, the mop element 20 is fitted to the transmission assembly 40 and is spaced with the main brushes 30, and the element of the mop element 20 can rotate under the action of the transmission assembly 40, so that, under the action of the transmission assembly 40, the ring-shaped cleaning surface can circulate the contact surface with the floor for cleaning, which increases the contact surface between the mop element 20 and the floor, thus improving the cleaning surface for a single pass, the cleaning efficiency and the cleaning effect. In addition, the surface area of ​​the mop element 20 is increased, so that when cleaning the same floor area, the mop element 20 is not easy to get dirty, this means that the cleaning surface of the mop element 20 after washing is larger.After the main brush 30 has removed the debris from the floor surface, the mop element 20 can sweep the floor to clean stubborn stains, while preventing debris from affecting the effect of the mop element 20, thus ensuring a thorough cleaning effect and improving the user experience.

[0042] With reference to Figures 1 and 2, in certain embodiments, in order to prevent waste from affecting the cleaning effect of the mop element 20, along the direction of movement of the cleaning device 100, the main brushes 30 are located in front of the mop element 20, i.e. that in the process of movement of the cleaning device 100, the main brush 30 first cleans the waste and dust, then the mop element 20 cleans the floor, and cleans stubborn stains on the floor, and the waste does not interfere with the action of the mop element 20, thus ensuring the cleaning effect of the mop element 20, which further guarantees the cleaning effect.

[0043] With reference to Figures 1 and 2, in certain embodiments, in order to allow the mop element 20 to move along a contact surface with the floor for cleaning, the transmission assembly 40 comprises: a first transmission element (not shown in the figures) and a second transmission element (not shown in the figures). The first transmission element is rotatably arranged in the housing 10. The mop element 20 is fitted to the first and second transmission elements, and the first element the first transmission element and the second transmission element rotate in the same direction, and the transmission of the first transmission element and the second transmission element causes the rotation of the mop element 20, forming a tracked sweeping structure, increasing the surface area of ​​the mop element 20, and thus contributing to the improvement of the cleaning surface of the cleaning device 100.

[0044] In some embodiments, the first transmission element and the second transmission element are spaced so that the first transmission element and the second transmission element can support the mop element 20 to ensure that the drive of the first transmission element and the second transmission element causes the rotation of the mop element 20.

[0045] In some embodiments, at least one of the first and second transmission elements may be connected to a power source, such that the driving force of the power source can rotate the first and second transmission elements, thereby enabling the mop element 20 to rotate. For example, the cleaning robot 100 may also include a transmission assembly, and the transmission assembly may include a drive motor, a gearbox, and other structures. The transmission assembly is connected to the first transmission element; or the transmission assembly is connected to the second transmission element; or the transmission assembly is connected to both the first and second transmission elements.

[0046] In some embodiments, the transmission assembly can be mounted on the housing 10; alternatively, the transmission assembly may not be mounted on the housing 10, and the transmission assembly can be coupled to the transmission assembly 40 by other structures, such as a support, so that the transmission assembly 40 and the transmission assembly can be mounted on or removed from the housing 10 together.

[0047] In certain embodiments, under the rotation of the first transmission element, the mop element 20 can be driven in rotation on the first and second transmission elements so that the mop element 20 can circulate its contact surface with the floor for cleaning. This increases the contact surface of the mop element 20 with the floor, thus increasing the cleaning area in a single pass, improving cleaning efficiency and effect. Furthermore, the surface area of ​​the mop element 20 can be increased; when cleaning the same floor area, the mop element 20 is less likely to become soiled, meaning that the cleaning surface of the mop element 20 after a wash is larger. After the main brushes 30 have removed the debris from the floor surface, the mop element 20 can sweep the floor, in order to clean stubborn stains on the floor, while preventing waste from affecting the effect of the mop element 20, which still guarantees the cleaning effect and improves the user experience.

[0048] In some embodiments, the transmission assembly 40 also includes a pallet support (not shown in the figures). The first transmission element and the second transmission element are both mounted on the pallet support, and the pallet support is adapted to be removably connected to the housing 10, so that the transmission assembly 40 and the mop element 20 can be mounted and detached from the housing 10 via the pallet support. This is not only convenient and easy to install, but also allows the mop element 20 to be separated from the housing 10 without the user having to pull on the mop element 20. This also reduces the number of pulls on the mop element 20, which helps to extend the service life of the mop element 20.

[0049] In certain embodiments, to more clearly describe the behavior of the cleaning device 100, the following orientation is defined: the cleaning device 100 can move on the ground by various combinations of movements about three mutually perpendicular axes defined by the housing 10: a transverse axis x, a front and rear axis y, and a central vertical axis z.
