Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and more specifically to a multifunctional surface cleaning device. Background Art

[0002] With the development of the times and the improvement of living standards, vacuum cleaners, especially household vacuum cleaners, have been widely used. This type of surface cleaning device mainly uses an electric motor to generate negative air pressure in a sealed housing, so that dust and garbage can be sucked in to complete cleaning. Its main function is to recycle and clean dust and garbage on the floor, carpet, etc. at home. At present, most cleaning devices recycle and separate dust, hair and other garbage by setting a dust cup on the body. Large particles of dust and hair and other garbage are sucked into the floor brush and then enter the dust cup for dust and gas separation. For example, the utility model patent with publication number: CN203861124U discloses a vacuum cleaning device, including a body, a dust cup, a mop, and a cord reel, the motor is in the motor housing, and an air outlet filter is connected to the motor housing; the dust cup is connected to the body, the dust cup includes a cup body, a cup cover, and a bottom cover, the cup cover includes a dust cup outer cover and a dust cup inner cover, an inner sealing ring is provided between the dust cup inner cover and the cup body, a filter cover, a dust cup filter, and a transparent tube are provided in the dust cup, the dust cup filter is sleeved outside a cyclone separator, and a roller brush is provided on the mop; in this technical solution, garbage, impurities and dust are separated by a dust cup to ensure smooth pipeline operation, avoid damage to the internal structure, and extend the service life, but a single dust cup must separate large particles of dust and hair as well as fine particles of dust, and the separation efficiency of a single dust cup is limited, and the dust and gas separation efficiency is low, which affects the cleaning efficiency. On the other hand, the current surface cleaning device has a relatively simple usage mode, which is difficult to meet the various usage needs of users. In order to solve this technical problem to a certain extent, some push-stick vacuum cleaners with detachable portable handheld vacuum cleaners have appeared. When the handheld vacuum cleaner is removed from the push-stick vacuum cleaner, the handheld cleaning mode can be realized. When the handheld vacuum cleaner is installed on the push-stick vacuum cleaner, the upright cleaning mode can be realized. However, the handheld vacuum cleaner needs to select a smaller power suction motor in consideration of its portability, which affects the cleaning effect. Moreover, when the handheld vacuum cleaner is used alone, it needs to rely on its own battery pack for power supply. Considering the convenience, the handheld vacuum cleaner has a smaller battery pack, and the battery pack power is limited. Even after being fully charged, the time available for a single use is very short. There are still many problems in actual use. Utility Model Content

[0003] The technical problem to be solved by the present application is to provide a multifunctional surface cleaning device, which improves the cleaning efficiency by cooperating with a first cyclone separation dust cup and a second cyclone separation dust cup to synchronously separate dust and gas. By providing a detachable first connecting tube, the first connecting tube can be used alone for dust collection after being separated from the main unit, thereby increasing the usage modes of the surface cleaning device and being labor-saving and convenient to use.
