[0039] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0041] Furthermore, certain terms are used in the specification and subsequent claims to refer to specific components or parts. Those skilled in the art will understand that manufacturers may use different names or terms to refer to the same component or part. This specification and subsequent claims do not distinguish components or parts by differences in name, but rather by differences in function.

Additionally, the term "connection" here includes any direct and indirect means of connection. Indirect means of connection include connections via other means.

[0042] like Figure 1 As shown, and in conjunction with reference Figures 2A-2C A preferred embodiment of the cleaning device 100 of the present invention is, for example, a floor mop, which mainly includes a main unit 10, a cleaning mechanism 20, and a magnetic attachment mechanism 30 (see details for specific structure). Figures 2A-2C The magnetic attachment mechanism 30 is provided corresponding to the cleaning mechanism 20 and can provide a magnetic force to the cleaning mechanism 20, thereby adjusting the friction between the cleaning mechanism 20 and a surface to be cleaned (e.g., the ground).

[0043] In this embodiment, as Figures 2A-2C As shown, the main unit 10 may include a body 11 and a water tank 12. The water tank 12 may include a main body 121 and a lower cover 122, with the lower cover 122 detachably mounted to the main body 121. The assembled water tank 12 can be detachably mounted to the body 11, for example, within a water tank slot 101 on the body 11, and supported from below by two opposing support portions 110 located within the slots 101. In this invention, the main unit 10 may also include a power motor (not shown) and a cleaning brush 14, wherein the power motor may include, for example, a motor that provides driving force for at least one of the following: sweeping, vacuuming, or moving of the cleaning equipment.

[0044] In the present embodiment, as shown in Figure 2A the cleaning mechanism 20 may, for example, include a cleaning bracket 21 and a cleaning mop 22. The cleaning mop 22 is detachably mounted on the cleaning bracket 21. The cleaning mechanism 20 may, for example, be detachably mounted on the main machine 10 by cooperating the first mounting member 22 provided on the top of the cleaning bracket 21 with the second mounting member 13 provided on the main machine 10. A through hole 214 is further provided on the cleaning mechanism 20 to allow water in the water tank main body 121 to flow to the cleaning mop 22 to wet the cleaning mop 22, so that the wet cleaning mop 22 can be used to mop the floor.

[0045] In the present embodiment, as shown in Figure 2C the magnetic force adding mechanism 30 may, for example, include a single first magnet 31 and a single second magnet 32. The first magnet 31 is provided on the cleaning mechanism 20, for example, is centrally mounted on the top of the cleaning bracket 21 through a mounting space 213. The second magnet 32 is provided on the main machine 10 corresponding to the first magnet 31, for example, is centrally mounted on the bottom of the water tank lower cover 112. Preferably, the second magnet 32 is mounted on the inner side of the water tank lower cover 112. In other embodiments, the second magnet 32 can also be mounted on the outer side of the water tank lower cover 112.

[0046] In the present application, the second magnet 32 interacts with the first magnet 31 to generate the magnetic force, which may, for example, be magnetic repulsion or magnetic attraction. The present application adds the magnetic force to the cleaning mechanism to adjust the friction between the cleaning mechanism and the cleaned surface. For example, including but not limited to, when cleaning, the friction between the cleaning mechanism 20 and the cleaned surface (e.g. floor) can be increased by adding magnetic repulsion to the cleaning mechanism 20, so that the cleaning rate can be effectively improved. When cleaning is completed, the friction between the cleaning mechanism 20 and the cleaned surface can be reduced or even eliminated by adding magnetic attraction to the cleaning mechanism 20, so that the cleaning mechanism 20 can be separated from the cleaned surface, thereby improving the obstacle crossing ability of the cleaning device 100, or avoiding damage to the cleaned surface (e.g. wooden floor) caused by residual water on the cleaning mechanism 20 due to long-term stay of the cleaning device 100.

[0047] In the present application, the first magnet 31 and the second magnet 32 can both be permanent magnets, and the magnetic force generated by the two magnets may, for example, be magnetic repulsion, i.e. pressure can be added to the cleaning mechanism 20, so that the friction between the cleaning bracket and the cleaned surface (e.g. floor) can be increased during cleaning, so that the cleaning rate can be effectively improved.

[0048] Alternatively, the first magnet 31 can be a permanent magnet, and the second magnet 32 can be an electromagnet (for example, including but not limited to an electromagnetic coil). The magnetic force generated by the two magnets can be magnetic repulsion or magnetic attraction. In this case, the magnetic force adding mechanism 30 of the present application can further include a current control unit (not shown in the figure) electrically connected to the second magnet 32. The direction or size of the current flowing through the second magnet 32 can be controlled by the current control unit. For example, when the cleaning device 100 of the present application is a magnetic pressure added mop, the presence or absence of magnetism can be controlled by turning on or off the electromagnetic coil (i.e. the second magnet), the strength of the magnetism can be changed by the size of the current, and the magnetic pole can be changed by the direction of the current, so that the control of the cleaning device 100 of the present application is more flexible and variable. In other words, the present application not only adjusts the added magnetic force (for example, adjusts the magnetic force to be magnetic repulsion or magnetic attraction), but also adjusts the size of the magnetic force, so that the cleaning rate can be adjusted and controlled according to actual needs or different scenarios.

[0049] As shown in Figures 3A-3C , which shows the structure of another preferred embodiment of the cleaning device 100 of the present application. Different from the embodiment shown in Figures 2A-2C , the magnetic force adding mechanism 30 of the cleaning device 100 of the embodiment shown in Figures 3A-3C includes two first magnets 31 (i.e. 31a and 31b) and two second magnets 32 (i.e. 32a and 32b). The two first magnets 31a and 31b can be arranged on the two sides of the top of the cleaning bracket 21 through two mounting spaces 213a and 213b, respectively. The two second magnets 32a and 32b can be arranged on the two sides of the bottom of the lower cover 122 of the water tank and correspond to the two first magnets 31a and 31b through two mounting spaces 122a and 122b, respectively. This way of arranging magnets on both sides can make the force on the cleaning mechanism 20 more uniform, so that the cleaning effect is better.

[0050] In the embodiment shown in Figures 3A-3C , the two first magnets 31a and 31b can be permanent magnets. The two second magnets 32a and 32b can be permanent magnets or electromagnets. In this way, magnetic repulsion and / or magnetic attraction can be generated by the interaction of the first magnet 31 and the second magnet 32.

[0051] In the embodiment shown in Figures 2A-2C and Figures 3A-3CIn the illustrated embodiment, the cleaning device 100 of the present invention is described using a floor mop as an example, and the magnetic attachment mechanism 30 employs a single magnet and two magnets interacting to generate magnetic force. However, it is understood that in other embodiments, the cleaning device 100 of the present invention can also be a sweeping machine with a mopping function or any other suitable device, and the present invention does not limit this. Furthermore, the magnets of the magnetic attachment mechanism 30 can also be configured to employ, for example, three, four, or more magnets interacting, and these are also not considered limitations of the present invention.

[0052] like Figure 4 As shown, a cleaning method 200 of the present invention is illustrated, comprising:

[0053] Step S1: Provide cleaning equipment.

[0054] Step S2: A magnetic force is applied to the cleaning mechanism through the magnetic attachment mechanism of the cleaning equipment to adjust the friction between the cleaning mechanism and the surface to be cleaned.

[0055] The cleaning equipment may be, for example, a Figures 2A-2C and Figures 3A-3C The cleaning device of the illustrated embodiment includes a first magnet and a second magnet. Step S2 may include:

[0056] Step S21, the interaction between the first magnet and the second magnet provides a magnetic repulsive force to the cleaning mechanism to increase the friction between the cleaning mechanism and the surface being cleaned; and / or,

[0057] Step S22: The interaction between the first magnet and the second magnet provides a magnetic attraction force to the cleaning mechanism to reduce the friction between the cleaning mechanism and the surface being cleaned.

[0058] This invention adjusts the friction between the cleaning mechanism and the surface being cleaned by applying magnetic force to the cleaning mechanism. For example, by applying magnetic repulsion to the cleaning mechanism during cleaning, the friction between the cleaning mechanism and the surface being cleaned can be increased, effectively improving the cleaning efficiency. By applying magnetic attraction to the cleaning mechanism at the end of cleaning, the friction between the cleaning mechanism and the surface being cleaned can be reduced or eliminated, allowing the cleaning mechanism to detach from the surface. This improves the obstacle-crossing ability of the cleaning equipment or prevents damage to the surface being cleaned (e.g., wooden flooring) caused by residual moisture on the cleaning mechanism due to prolonged use.

[0059] Furthermore, the first magnet may be a permanent magnet, while the second magnet may be an electromagnet, and the cleaning method 200 may further include:

[0060] Step S3, controlling the current flowing through the second magnet by a current control unit electrically connected with the second magnet to adjust the magnetic force to be magnetic repulsion or magnetic attraction, or adjust the size of the magnetic force. In this way, the cleaning rate can be adjusted and controlled according to actual needs or different scenarios.
