At present, household vacuum cleaners are mainly dry vacuum cleaners, which only have the function of vacuuming. Dry vacuum cleaners are mainly used to absorb dry garbage such as dust and particles. After the dust collecting device of the dry vacuum cleaner is full, the dust inside needs to be cleaned so that the dry vacuum cleaner can continue to work; although there are dry and water-absorbing dual-purpose vacuum cleaners on the market, the separation efficiency of traditional dry and water-absorbing dual-purpose vacuum cleaners is low during vacuuming, which easily causes fine dust to clog the filter system of the dry and water-absorbing dual-purpose vacuum cleaners, which reduces the performance of the dry and water-absorbing dual-purpose vacuum cleaners, the vacuuming effect is poor, and the user experience is poor. In addition, the traditional dual-purpose vacuum cleaners are noisy and unfriendly to users.

An exhaust hole 1a is opened on the side of the top of the cylinder 1, and the air outlet of the exhaust fan 16 is connected to the exhaust hole 1a; the cylinder 1 includes an inner plate 1-1 and an outer plate 1-2, and a wave-shaped bending plate 1-3 is fixed between the inner plate 1-1 and the outer plate 1-2, and a cavity 1-3a is opened in the bending plate 1-3, and the cavity 1-3a The inside is filled with water 1-4, the gap between the bending plates 1-3 is filled with sound insulation cotton 1-5, a group of rubber strips 1-6 evenly distributed along the arc direction of the cylinder 1 are fixed on the inner plate 1-1 and the outer plate 1-2, and the bending plate 1-3 is supported on the rubber strips 1-6; a liquid chamber 1b is between the bottom end of the cylinder 1 and the dust particle collecting cylinder 1c, and a liquid outlet pipe 17 passing through the cylinder 1 is installed on the liquid chamber 1b, and a slag outlet pipe 18 passing through the cylinder 1 is installed at the dust particle collecting cylinder 1c, and a sealing cover 19 is threadedly connected to the liquid outlet pipe 17 and the slag outlet pipe 18.

[0035] The metal filter plate 5 is composed of an upper metal filter plate 5-1 and a lower metal filter plate 5-2. The V-shaped cone angle of the upper metal filter plate 5-1 is greater than the V-shaped cone angle of the lower metal filter plate 5-2.

[0036] An air inlet pipe 20 is installed at the air inlet of the exhaust fan 16 , the filter screen cover 17 is installed at the air inlet pipe 20 , and a group of vibrators 21 evenly distributed along the center of the air inlet pipe 20 are installed at the air inlet pipe 20 .

A group of connecting plates 24 evenly distributed along the center of the cylinder 1 are fixed between the circular sleeve 22 and the cylinder 1; a rubber pad 25 is installed between the support 7 and the drive motor 8.

[0038] A liquid level gauge 1d for measuring the liquid level in the liquid holding chamber 1b is installed on the cylinder 1.

[0039] A limiting sleeve 4-1 is fixed to the bottom end of the second annular seat 4 and is sleeved on the top end of the dust particle collecting tube 1c.

[0040] A self-lubricating layer 4 - 1 a is provided on the inner contour surface of the limiting sleeve 4 - 1 .

[0041] A pair of universal wheels 26 and a pair of rollers 27 are installed at the bottom of the cylinder 1 .

[0044] The working principle of the present invention is as follows: when it is necessary to vacuum or absorb water from the ground, it is only necessary to press the first switch 29 and the second switch 30 first. If the dust sucked is dust without liquid, the exhaust fan 16 is started, so that the suction cup 15 generates a strong suction force, thereby cleaning the ground or the carpet, so that the dust, impurities and particles are sucked into the circular pipe 11 through the suction tube 14, and then sucked into each bending pipe 12, and then discharged through the arc opening 13-1 on the nozzle 13. The dust, impurities and particles are then filtered by the filter screen 17 (heavier and larger particles will directly pass through the blocking of the metal filter plate 7 and fall directly into the dust particle collection tube 1c), and the clean gas will be discharged through the exhaust hole 1a. At this time, the high-speed rotating metal filter plate 5 does not play a big role; when the suction cup 15 sucks impurities and particles (water stains) with water, at this time, the gear 10 is driven to rotate at a high speed through each driving motor 8, so that the circular rack 9 can also be driven to rotate at a high speed, and the first circular ring seat 3 can be driven to rotate at a high speed. , and then drives the metal filter plate 5 to rotate at a high speed. At this time, the water with impurities and particles (it can also be pure water) is sucked into each bending tube 12 and then discharged through the arc mouth 13-1 on the nozzle 13. It will be sprayed to the high-speed rotating metal filter plate 5 for filtration through the action of gravity, and the filtered water will fall into the liquid holding chamber 1b. The filtered impurities and particles will fall into the dust particle collecting barrel 1c for collection through gravity, thereby achieving dry and wet dual-use, and the dust and water absorption filtering effects are good, and the filter screen cover 17 will not be blocked, and the user experience is good. The dust on the filter screen cover 17 is shaken off by the vibration of the vibrator 21, and will also be collected by the dust particle collecting barrel 1c through gravity, thereby achieving a good dry and wet dual-use effect, without the need for manual mode switching, and the user experience is good; because the cylinder body 1 adopts a noise reduction design and uses the vibration reduction design of the inclined spring 23 and the rubber pad 25, the dust and water suction machine has extremely low noise during operation, which can achieve a silent effect and is worthy of promotion and application.
