[0021] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments as a further preferred explanation:

[0022] refer to Figure 1-Figure 4 , a floor cleaning device, comprising a lower body 100 and an upper body 200 connected to each other;

[0023] The lower body 100 includes a lower body shell 110 and a drum 120. The drum 120 is arranged inside the lower body shell 110 and exposed to the outside. A scraper 130 for scraping foreign matter on the drum 120 is arranged inside the lower body shell 110. A suction hood 140 for absorbing foreign matter by negative pressure is arranged next to the drum 120. The scraper 130 is close to the suction hood 140 so that the scraped foreign matter is directly sucked away by the suction hood 140. A nozzle 150 for spraying water to clean the drum 120 is arranged next to the drum 120.

[0024] The upper body 200 includes an upper body shell 210, in which a clean water tank 220 for containing cleaning liquid, an electric motor 230 for providing negative pressure and a dirt collecting barrel 240 for containing dirt are arranged. The dirt collecting barrel 240 is connected to the suction hood cylinder 140 through a pipe system. The electric motor 230 is connected to the pipe system to provide negative pressure and sucks foreign matter from the suction hood cylinder 140 into the dirt collecting barrel 240. The clean water tank 220 is connected to the nozzle 150 through a pipe to spray water, and a pressurizing device for pressurizing water is arranged on the pipe connected to the nozzle 150.

[0025] In the specific implementation process, the connection between the lower body 100 and the upper body 200 forms the main body of the whole product, which is used to set various functional components, and provide an adaptive assembly structure for the shape of each functional component itself, and a derivative structure for setting the assembly of each functional component. When the product adopting this solution is working, the drum 120 rolls to complete the cleaning of the ground, and when cleaning, the drum 120 will inevitably absorb dirt. Therefore, the clean water in the clean water tank 220 enters the nozzle 150 through the action of the pipeline and the pressure device, and then sprays onto the drum 120 to achieve cleaning. Generally speaking, the outer surface of the drum 120 has water absorption, because water absorption is also a necessary performance as a cleaning tool. Therefore, when the drum 120 is sprayed with water, it can clean the drum 120. At the same time, due to the scraping action of the scraper 130 on the drum 120, the surface of the drum 120 will be deformed, squeezing out the sewage, and then under the action of negative pressure, it is sucked into the sewage collection barrel 240 through the suction cover tube 140 and the pipe system to complete the collection and accommodation of the sewage. There are many types of pressurizing devices, such as water pumps and solenoid valves.

[0026] In the specific implementation, as a preferred embodiment, the roller 120 is a flock roller or a velvet roller. The flock roller is used for surfaces that are difficult to clean, such as carpets. The velvet roller is a common roller 120, which is suitable for flat floors.

[0027] In the specific implementation, as a preferred embodiment, the suction cover cylinder 140 includes an open cover shell 141 and a wind tube portion 142 arranged in the middle of the cover shell 141, the cover shell 141 faces the drum 120, and the wind tube portion 142 is connected to the pipe system. In this preferred embodiment, a specific structural form of the suction cover cylinder 140 is specifically provided, through which it is convenient to fully absorb water from the drum 120 and ensure the effect of negative pressure water absorption.

[0028] In the specific implementation, as a preferred embodiment, the scraper 130 is arranged throughout the axial direction of the drum 120. In this preferred embodiment, the scraper 130 is arranged throughout the drum to ensure the scraping and washing effect.

[0029] In the specific implementation, as a preferred embodiment, the edge of the cover shell 140 corresponds to the edge of the drum 120. In this preferred embodiment, the edge of the cover shell 140 is flush with the edge of the drum 120 to ensure that the effect of the negative pressure is sufficient.

[0030] In the specific implementation, as a preferred embodiment, the scraper 130 is fixedly arranged on the suction cover 140 and close to the upper position of the drum 120. In this preferred embodiment, by fixing the scraper 130 on the suction cover 140, the rationality and reliability of its position are guaranteed. The upper position close to the drum 120 is mainly considered that the scraped sewage will flow down under the influence of its own gravity. If it is located at the top, it can meet the effect of being sucked away by negative pressure. If it is located in the middle or lower position, the sewage is easy to flow out directly and cannot be sucked away by negative pressure.

[0031] In the specific implementation, as a preferred embodiment, the nozzle 150 is fixedly arranged on the suction cover 140 and is located above the scraper 130. In this preferred embodiment, the position of the nozzle 150 is convenient for water discharge for cleaning, and cooperates with the function of the scraper 130 to make the flushing and scraping effects better.

[0032] In the specific implementation, as a preferred embodiment, a roller placement member 160 for placing a spare roller is provided on the lower body shell 110. As above, a plurality of rollers may be provided in the specific implementation, therefore, the roller placement member 160 is provided to facilitate the placement of the spare roller.

[0033] In the specific implementation, as a preferred embodiment, a battery placement member 170 for placing a backup battery is provided on the lower housing 110. The battery placement member 170 is used to place a backup battery, and the battery is used to power various components of the circuit system.

[0034] In a specific implementation, as a preferred embodiment, a drum motor for driving the drum 120 to rotate is disposed in the lower housing 110 .

[0035] In a specific implementation, in order to protect the entire device when not in use, a storage seat 180 is provided.

[0036] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
