Abstract

Since there are many surfaces in the home environment that are not suitable for wet cleaning, such as carpets and the like; in order to prevent wetting of the carpet surface, some robots may bypass the carpet surface, which may cause the carpet surface to become a blind cleaning zone; meanwhile, when a surface unsuitable for wet cleaning, such as a carpet, is divided into isolated areas, a cleaning blind area may occur. Therefore, the cleaning robot can be automatically connected with the water tank, so that the cleaning work of the surface suitable for wet cleaning such as a floor can be finished when the surface suitable for wet cleaning is separated into isolated areas by the surface not suitable for wet cleaning.

Preferred embodiments of the present application are given in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, this embodiment is provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "front", "back", and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

Referring to fig. 1 to 5, the present embodiment provides a cleaning robot including a cleaning robot main body 10 and a water tank assembly 20. The cleaning robot main body 10 in this embodiment has a roll brush 13, a drive wheel 15, and an electromagnet 16 located behind the cleaning robot main body 10. The cleaning robot main body 10 can be operated alone using components such as the roller brush 13, and dry-cleans a surface to be cleaned, such as a carpet, which is not suitable for wet cleaning. The cleaning robot main body 10 can also be connected with a water tank assembly 20 to work together, the water tank assembly 20 is provided with a water tank circuit 21, a water storage tank 22, an iron sheet 23 and the water tank assembly 20 also comprise a mopping floor 24 and a driven wheel 25; when the electromagnet 16 is connected with the iron sheet 23, the water tank assembly 20 is connected to the cleaning robot main body 10, the water tank assembly 20 can move together with the cleaning robot main body 10 through the cooperation of the driven wheel 25, the water discharged from the water tank 22 wets the floor mopping 24, and at this time, the cleaning robot can perform wet cleaning such as mopping on the floor, ceramic tile and other surfaces to be cleaned which are suitable for wet cleaning. Among them, the water tank assembly 20 may be provided in number so as to work with the cleaning robot main body 10 in each isolated region.

With continued reference to fig. 6 and 7, when the cleaning robot encounters the situation illustrated in the figure, i.e., the first area a and the third area C are both floor surfaces, and the second area B is a carpet surface, the cleaning robot identifies the surface type of the floor surface by the identification component having the identification component circuit 12 for the purpose of not wetting the carpet. Referring to fig. 1 to 8, the cleaning robot body 10 further has an identification component capable of identifying the surface type of the surface to be cleaned, the identification component circuit 12 includes a first infrared transmitting tube 121 and a first infrared receiving tube 122, when the surface to be cleaned is a carpet surface unsuitable for wet cleaning, due to unevenness of the carpet surface, the infrared rays transmitted by the first infrared transmitting tube 121 are absorbed or diffusely reflected by the carpet surface, and the first infrared receiving tube 122 rarely or hardly receives the reflected infrared rays. At this time, the I/02 port of the identification component circuit 12 shown in fig. 8 outputs a high level, and the identification component identifies the surface to be cleaned as a surface of carpet type unsuitable for wet cleaning; when the surface to be cleaned is a floor, the first infrared receiving tube 122 can receive the reflected infrared ray, and at this time, the I/02 port of the circuit 12 of the identification component outputs a low level, and the identification component identifies the surface to be cleaned as a surface suitable for wet cleaning, such as a floor.

Referring to fig. 6 and 7, when the cleaning robot is about to clean the first area a, and it is detected that the first area a is a floor surface, the cleaning robot body 10 is connected to the water tank 20. Referring to fig. 5 and 8-10, the tank circuit 21 is connected to a battery 213, a transmitting assembly and a detecting assembly for detecting whether the tank assembly 20 is connected to the cleaning robot main body 10, wherein the transmitting assembly is a second infrared transmitting assembly 211 in the present embodiment; the detection member is a hall element 212, which is located near the iron sheet 23 on the water tank assembly 20, and detects a change in the magnetic field to determine whether the cleaning robot main body 10 is separated from the water tank assembly 20. When the separation of the water tank assembly 20 from the cleaning robot main body 10 is detected, the second infrared transmitting assembly 22 transmits a signal to indicate the position of the water tank assembly 20. The receiving component 14 arranged on the cleaning robot main body 10 controls the driving wheel 15 through the control component 11 according to the signal transmitted by the second infrared transmitting component 211 to enable the cleaning robot main body 10 to move and search the water tank component 20, when the receiving component 14 determines that the cleaning robot main body 10 searches the water tank component 20 according to the signal change of the second infrared transmitting component 211, the control component 11 on the cleaning robot main body 10 controls the electromagnet 16 to be electrified, and at the moment, the electromagnet 16 generates suction force, so that the iron sheet 23 can be attracted; meanwhile, the hall element 212 of the water tank assembly 20 detects that the cleaning robot main body 10 is connected to the water tank assembly 20, and controls the second infrared transmitting assembly 211 to stop transmitting the signal. At this time, the cleaning robot main body 10 is stably coupled to the water tank assembly 20 and can move together and clean the surface to be cleaned.

Referring to fig. 6 and 7, after the first area a is cleaned, when the recognition component of the cleaning robot recognizes that the second area B is a carpet surface unsuitable for wet cleaning, the cleaning robot main body 10 controls the electromagnet 16 to be powered off through the control component 11, so as to be disconnected from the water tank component 20, thereby preventing the carpet surface of the second area B from being polluted. When the cleaning of the carpet surface of the second area B is completed, the cleaning robot main body 10 enters the floor surface of the third area C suitable for wet cleaning, and the recognition component recognizes that the surface to be cleaned by the cleaning robot main body 10 is the floor. The control assembly 11 of the cleaning robot main body 10 then controls the cleaning robot main body 10 to walk and connects the same water tank assembly 20' as the water tank assembly 20 in the same manner as described above, and then cleans the floor surface in the third region C.

The above-mentioned embodiments only represent the preferred embodiments of the present solution, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the patent. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present solution, which falls within the protection scope of the present solution. Therefore, the protection scope of the present patent shall be subject to the appended claims.
