the embodiment is further optimized on the basis of any one of the above embodiments, and in order to further better implement the utility model, the following arrangement structure is particularly adopted:

in this embodiment, the filter element assembly 2 further includes a water pan 25 coaxially disposed with the filter element 23, the water pan 25 is configured as a tapered tube structure with a large top and a small bottom, the top of the water pan 25 is connected to the bottom of the lower bracket 21, and the inner diameter of the bottom of the water pan 25 is smaller than the diameter of the through hole of the lower bracket 21, so that the bottom of the water pan 25 is closer to the rotation axis than the inner edge of the through hole of the lower bracket 21 and the inner wall of the filter element 23 or the inner wall of the filter screen 24 inside the filter element 23.

The filter element assembly 2 is detachably inserted into the upper shell cover 7 from top to bottom through the air outlet 71, and the bottom end of the water pan 25 of the filter element assembly 2 is detachably seated at the bottom of the water box 8.

In this embodiment, the structure of the water pan 25 can receive the water drops dropping from the filter element assembly 2, and the water pan 25 is of a tapered tube structure with a large upper part and a small lower part, so that the water drops can be effectively eliminated, and the working noise is reduced.

Example 9:

the present embodiment is further optimized based on any of the above embodiments, and in order to further implement the present invention, the following setting structure is particularly adopted:

in this embodiment, the outer edge of the upper cover 22 of the filter element assembly 2 is provided with a ring of wind shielding walls 22a extending downward along the outer side of the filter element 23, and the wind shielding walls 22a are used for compressing the vertical distance of the annular windows to reduce the size of the passage for the overfire wind.

In this embodiment, the wind shielding wall 22a can reduce the exposed area of the outer side of the filter element 23, so that the airflow enters from the lower part of the filter element 23 more and moves upwards, thereby increasing the purification path and purification time of part of the airflow, and simultaneously, more airflow can be more fully purified with the water sprayed by the spraying device 1.

When the purifying and humidifying integrated machine is used, the driving device 4 drives the fan blade 3 and the driving shaft 5 to rotate, the fan blade 3 enables air to enter the lower casing cover 6 through the air inlet 61 to form airflow, the airflow flows from bottom to top and flows upwards from the annular part between the water box 8 and the lower casing cover 6 and the upper casing cover 7 and flows to the outer side position of the filter element assembly 2 through the gap between the installation seat of the upper casing cover 7 and the water box 8, and because the connection part of the filter element assembly, the water box 8 and the upper casing cover 7 has air tightness, the airflow passes through the filter element 23 after passing through the filter screen 24 sleeved on the filter element 23 and then passes through the filter screen 24 on the inner side of the filter element 23 and then enters the annular part between the filter element assembly 2 and the spraying device 1, and then passes upwards from the top of the filter element 23 and then is discharged through the through-hole air outlet 71 on the top of the upper casing cover 7.

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 filter element group spare 2 can dismantle with water box 8 and go up the cap 7 and be connected, and filter element group spare 2 seat connects on water box 8, 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 an alkalescent adsorption solution (the type of the solution stored in the solution cavity can be selected according to the type of pollutants in the air), sodium hydroxide is mainly used, and the PH value of the water body is adjusted to 9.0-10.0, in order to improve the purification effect, in order to solve the problem of the environment with more acidic pollutants, 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, acetic acid and benzoic acid are mainly used, and the PH value of the water body is adjusted to 2.0. 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 scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
