Problems solved by technology
Although the sewage recovery channel of this type of patented product is separated from the driving air channel of the wind impeller, and has a separate water suction channel and sewage suction nozzle, in order to ensure the function of the suction nozzle of this type of product, its size is limited, resulting in the suction nozzle. Insufficient air flow and specifications for vacuuming
As a result, the air inlet of this type of pneumatic cleaning brush can only clean sewage but is difficult to use for dust removal

Embodiment 1
[0028] This embodiment is a multi-purpose cleaning brush for vacuum cleaners, the specific structure is shown in Figure 1, the upper and lower parts of the middle frame 1 are respectively buckled to cover the front cover 2 and the bottom cover 3, forming a complete machine case.
[0029] The rear end of the casing forms a tubular outlet, and there is a suction port below. The interior is divided into upper and lower chambers. The upper chamber is equipped with an airflow-driven impeller assembly 6, and the lower chamber is equipped with a roller brush assembly 7 connected to the impeller assembly through a belt 8. There is an opening between the upper and lower chambers. One side of the impeller in the casing is provided with a sewage recovery channel 15 isolated from the impeller. One end of the sewage recovery channel 15 communicates with the outlet, and the other end faces the water inlet 14 of the middle frame.
[0030] The front cover 2 of the housing is provided with a...

The invention relates to a multipurpose cleaning device with functions of absorbing water and dust, and belongs to the technical field of dust removal and cleaning appliances. There is an outlet at one end of the housing of the device, an air-driven impeller and a driven roller brush are installed inside, and a suction port is opened below; the housing is provided with a sewage recovery channel that is isolated from the impeller and communicated with the outlet; the housing is also equipped with a The air inlet is installed with a suction nozzle assembly having a water inlet and a water outlet; the suction nozzle assembly has a first position and a second position; when in the first position, the suction nozzle assembly closes the air inlet, and the suction port communicates with the outlet through the impeller ; When in the second position, the suction nozzle assembly closes the channel between the suction port and the impeller, the air inlet is opened and communicates with the outlet through the impeller, and the water outlet of the suction nozzle assembly communicates with the sewage recovery channel. During the working process, the invention can avoid the erosion of the sewage on the impeller and the transmission device. At the same time, it does not affect the air flow of the suction port, which can maintain the ideal dust collection effect.
Description
technical field [0001] The invention relates to a cleaning device with functions of absorbing water and dust, in particular to the structural improvement of the suction nozzle of the cleaning device, and belongs to the technical field of dust removal and cleaning appliances. Background technique [0002] At present, cleaning devices such as pneumatic vacuum cleaning brushes are not uncommon. The search found that US patents such as US5088149 and US6513190 disclosed related technologies respectively. However, this kind of product has no separate water suction channel and sewage suction nozzle because the dirty air recovery channel overlaps with the driving air channel of the wind impeller, so after long-term use, the sewage and solution flowing through the impeller will cause erosion to the bearing and transmission device damage. In fact, the air inlet of the above-mentioned pneumatic cleaning brush can only remove dust but cannot be used to remove sewage. [0003] In addi...
