[0002] With the development of economy and the improvement of living standards, household vacuum cleaners are widely used. At present, household vacuum cleaners are mainly dry vacuum cleaners, which only have the function of dust collection. Dry vacuum cleaners are mainly used to absorb dust and other dry garbage. When the dust collecting device of the dry vacuum cleaner is full of dust, the dust inside needs to be cleaned so that the dry vacuum cleaner can continue to work; although there are also wet and dry vacuum cleaners on the market, which are vacuum cleaners with both dust collection and water collection functions, the traditional wet and dry vacuum cleaners have low separation efficiency during dust collection, which easily causes fine dust to clog the filter system of the wet and dry vacuum cleaner, resulting in reduced performance of the wet and dry vacuum cleaner, poor dust collection effect, and poor user experience.

[0041] The working principle of the present invention is as follows: if dust without liquid is to be vacuumed, the exhaust fan 11 is started, so that a strong suction force is generated at the bottom of the cover shell 1-1. At this time, the driving motor 3 will drive the roller brush 2 to start, so as to clean the ground or the carpet, so that the dust, impurities and particles are sucked into the second connecting pipe 15, and then sucked into the annular guide cylinder 14, and then sprayed out through the air outlet 14-1.

At this time, the The impurities and particles with water are sucked into the annular guide tube 14 and then sprayed out through the air outlet 14-1. They will be sprayed to the high-speed rotating metal filter cover 7 for filtration through the action of gravity, and the filtered water will fall into the liquid holding tube 16. The filtered impurities and particles will fall into the dust particle holding tube 17 through the longitudinal through hole 7-1 for collection, thereby achieving both dry and wet use, and the dust and water absorbing filtration effects are good, the filter screen cover 12 will not be blocked, and the user experience is good. The dust at the filter screen cover 12 is shaken off by the vibration of the vibrator 23, and will also be collected by the dust particle holding tube 17 through gravity, thereby achieving a good dry and wet use effect, without the need to switch modes, and the user experience is good. When it is necessary to vacuum a small space, it is only necessary to close the solenoid valve 25 at the second connecting pipe 15, so that the suction pipe 24 removed from the block 4-4 has strong suction, which can be conveniently cleaned in both dry and wet conditions, and is worthy of promotion and application.
[0042] Although the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
