Cleaning device and method of using the same CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to Chinese patent application No. 202410231471.7 filed in China on February 29, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present invention relates to the technical field of cleaning devices, and in particular to a cleaning device and a method for using the same. Background Art

[0003] In the cleaning equipment sector, cleaning devices such as vacuum cleaners and floor scrubbers are widely used in domestic, industrial, and commercial environments. These devices are typically equipped with a wastewater tank to collect wastewater generated during the cleaning process. They are also equipped with a suction mechanism to draw wastewater and dirt into the tank.

[0004] However, in existing cleaning devices, the sewage tank and the suction device are typically directly connected. This ensures the normal operation of the suction device when the sewage tank is not full. However, when sewage accumulates to a certain level in the sewage tank, the suction device may continue to operate, generating excessive suction, causing the sewage in the sewage tank to flow back into the suction device.

[0005] Sewage backflow not only damages the suction device, disrupting its normal operation, but can also cause equipment failure, increasing maintenance and replacement costs. Furthermore, sewage backflow can cause safety issues, such as electrical short circuits. Therefore, preventing sewage backflow into the suction device when the sewage tank is overfilled has become a critical issue that needs to be addressed. Summary of the Invention

[0006] The problem solved by the present invention is that in the prior art, when sewage in a sewage tank of a cleaning device accumulates to a certain level, it may flow back into a suction device.

[0007] To solve the above problems, the present invention provides a cleaning device, which includes a suction component. The cleaning device also includes: a sewage tank, the sewage tank is provided with a sewage outlet and an exhaust port, and the suction component is connected to the sewage tank through the exhaust port; wherein, an anti-backflow structure is provided in the inner cavity of the sewage tank, and the anti-backflow structure is arranged between the sewage outlet and the exhaust port to separate the sewage outlet and the exhaust port.

[0008] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: the cleaning device includes a sewage tank, which is connected to the suction component. When the cleaning device performs the decontamination work, the suction component of the cleaning device works to generate suction, and the sewage or dirt on the surface of the object is sucked into the sewage tank through the handle. When the sewage in the sewage tank accumulates to a certain level, if the suction component continues to work at this time, it may generate excessive suction, causing the sewage in the sewage tank to flow back into the suction component. To this end, the present technical solution sets an anti-backflow structure between the sewage port and the exhaust port of the sewage tank to separate the sewage port and the exhaust port. In this way, the sewage will first enter the anti-backflow structure before entering the exhaust port. The anti-backflow structure prevents the sewage from flowing back into the suction component, thereby improving the stability and safety of the cleaning device and ensuring the user experience.

[0009] Furthermore, the sewage tank has a first cavity, the top portion of the sewage tank extends outward to form a boss, and the boss has a second cavity connected to the first cavity; the sewage outlet and the exhaust port are arranged on the lower end surface of the boss.

[0010] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: the first cavity is used to accommodate the sewage collected by the cleaning device during dirt removal, and a sewage outlet and an exhaust port are provided on the boss formed on the top of the cleaning device to prevent sewage from entering the suction assembly from the exhaust port.

[0011] Furthermore, the multiple partitions are a first partition, a second partition, a third partition and a fourth partition; wherein the first partition is sealedly connected to the inner surface of the boss to form a third cavity, the exhaust port is arranged in the third cavity, and a first opening is opened at the top of the first partition; the second partition, the third partition and the inner surface of the boss are sealedly connected to each other to form a fourth cavity, the third cavity is arranged in the fourth cavity, and a second opening is opened at a position near the edge of the boss on the second partition; the fourth partition is sealedly connected to the first partition and the second partition respectively to separate the fourth cavity, and a third opening is opened at the top of the fourth partition; the heights of the first opening, the third opening and the second opening are arranged in sequence from high to low.

[0012] Compared with the existing technology, the technical effect achieved by adopting this technical solution is as follows: through the arrangement of the first partition, the second partition, the third partition and the fourth partition, the exhaust port and the first cavity of the sewage tank are divided into multiple anti-backflow cavities, and an opening is provided in each anti-backflow cavity, and the openings are arranged in sequence from high to low from the cavity closest to the exhaust port to the cavity farther away, so that when there is too much sewage in the sewage tank, the cavity farther away from the exhaust port will be filled first, and then the cavity close to the exhaust port will be filled. This arrangement avoids the problem of sewage directly backflowing into the suction component through the exhaust port when there is too much sewage in the sewage tank.

[0013] Furthermore, the cleaning device includes: a shell, the shell has a first accommodating space and a second accommodating space, the sewage tank is arranged in the first accommodating space, and the suction component is arranged in the second accommodating space; a handle assembly, the handle assembly is connected to the sewage outlet through a first pipe; compared with the existing technology, the technical effect achieved by adopting this technical solution is: the suction component generates suction, and the sewage or dirt on the surface of the object is sucked into the sewage tank through the handle, thereby achieving the effect of cleaning the surface of the object.

[0016] Furthermore, the base is provided with a third chamber, the hot air duct and the cold air duct are respectively connected to the third chamber, and the base is provided with an air outlet connected to the third chamber.

[0017] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: the hot air and cold air generated by the suction component can be discharged out of the cleaning device through the third chamber on the base. At the same time, by using the same chamber to discharge the hot air and cold air, the utilization efficiency of the base space can be increased.
