Use the utility model discloses a during purification humidification all-in-one, drive device 4 drives fan blade 3 and 5 gyrations of drive shaft, fan blade 3 makes the air enter into through air intake 61 and forms the air current in the lower casing 6, the air current flows from bottom to top, from water box 8 with lower casing 6 and go up the annular space part between the cap 7 upwards flow and through go up the mount pad of cap 7 on with the clearance between the water box 8 flow to the outside position of filter element group spare 2, because the junction of filter element group spare and water box 8 and last cap 7 has the gas tightness, consequently the air current then through the cover establish enter into the annular space between filter element group spare 2 and the spray set 1 behind filter screen 24 on filter element 23 after through filter element 23 rethread filter element 23 inboard filter screen 24, later upwards again after through the filter element 23 top through the through-hole air outlet 71 discharge at upper casing 7 top.

In the process of air flow, the air flow passes through the outer filter screen 24, the filter element 23 and the inner filter screen 24 in sequence to carry out three-pass filtration, meanwhile, the air flow is filtered by water on the filter screen 24 and the filter element 23, and the air flow is divided into a plurality of small air flows by the filter screen 24 to be fully acted with the filter element and the water. When the air current is in filter element group spare 2, can be from bottom to top through the water smoke purifying area and the water curtain purifying area that spray set 1 formed and water sufficient collision takes place to filter.

In addition, because the filter element group spare 2 can be dismantled with water box 8 and go up the cap 7 and be connected, and the filter element group spare 2 seat connects on water box 8, the filter element group spare 2 can pass through in the air outlet 71 of cap 7, can conveniently demolish back with filter element group spare 2 and add water from the top to water box 8. Compared with the existing structure, the purification and humidification integrated machine has fewer accessories, is simple in assembling and combining process, can save production cost, and can realize the effect of convenience in use.

In order to improve the purification effect, a cleaning agent can be added into the water box 8 to make the water body in the water box 8 be a weakly alkaline adsorption solution (the type of the solution stored in the solution cavity can be selected according to the type of the pollutants in the air) and mainly sodium hydroxide is used, and the pH value of the water body is adjusted to 9.0-10.0, and in order to improve the purification effect, the cleaning agent can be added into the water box 8 to make the water body in the water box 8 be an acidic adsorption solution and mainly acetic acid and benzoic acid are used, and the pH value of the water body is adjusted to 2.0 in the environment with more alkaline pollutants. When the device is used, the spraying device 1 sprays solution on the filter element component 2, the air flow is treated to carry out sufficient gas-liquid exchange when upwards blowing in the filter element component 2 from the bottom, the solid formed by complexing the adsorption liquid and the pollutants in the air falls into the water box 8, so that the bacteria and the virus microorganisms can be killed when falling into the alkaline adsorption liquid or the acidic adsorption liquid, and the air is sterilized. The water mist sprayed by the spraying device 1 can also be attached to PM2.5 which is a condensation nucleus of the water mist in the air and fall into the adsorption liquid to achieve the purpose of purification.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
