The limiting portion 152 abuts against the drainage portion, and the support portion 151 abuts against the flow guiding portion of the humidification filter. The strength of the humidification filter as a whole can be enhanced by the arrangement of the limit end cover 150. At the same time, the wind generated by the wind turbine of the purifier is prevented from blowing up the humidifying filter.

Further, the water absorption of the filter substrate 250 is better than that of the humidification filter.

In this embodiment, by setting the water absorption of the filter substrate 250 to be superior to the water absorption of the humidification filter, the water filtration has sufficient water source at any time, so that the working efficiency of the humidification filter is effectively ensured.

Further, both ends of the return pipe 700 communicate with the water tank 900 and the water tank 400, respectively, and a constant flow structure 710 is formed on the inner wall of the return pipe 700. Thereby, excess water in the water tank 400 can flow back into the water tank 900 through the return pipe 700, thereby achieving recycling and water conservation. At the same time, through the steady flow structure 710 disposed on the inner wall of the return pipe 700, when the water flows along the inner wall of the return pipe 700, the flow of the steady flow structure 710 can slow down and stabilize the water flow, thereby making the water flow more stable. To reduce the noise generated by the water flow.

It will be understood that water in the water tank 400 flows back to the water tank 900 through the return pipe 700, and water flows downward from the upper side along the inner wall of the return pipe 700. In the process of using the conventional humidifying device, the flow of water in the return pipe 700 flows along the inner wall of the return pipe 700, and the flow rate is unstable, so that air is easily mixed at the water outlet of the return pipe 700 to form bubbles. The bubble burst produces noise. The humidifying device of the present invention has a buffering effect on the water flow by providing a steady flow structure 710 on the inner wall of the return pipe 700, so that the water flow is more stable, and the stabilized water flow is less likely to generate bubbles at the water outlet of the return pipe 700. Thereby, the noise generated by the bubble collapse can be avoided. Moreover, due to the buffering action of the above-mentioned steady flow structure 710 on the water flow, it is also possible to reduce the noise generated by the water flow falling to the water outlet due to the excessive speed.

According to the humidifying device of the embodiment of the present invention, by providing the flow regulating structure 710 on the inner wall of the return pipe 700, the water in the water tank 400 is returned to the water tank 900 through the return pipe 700, and the water is along the return pipe 700. When the inner wall flows, the steady flow structure 710 is provided to slow down and stabilize the water flow, thereby reducing noise.

A humidifying device according to an embodiment of the present invention will be described in detail below with reference to FIGS. 13-14.

In some embodiments of the present invention, the flow stabilizing structure 710 may include a plurality of elongated ribs and a groove defined between the plurality of ribs. Therefore, when the water flows along the inner wall of the return pipe 700, the water flow can be dispersed into each groove through the above-mentioned convex rib and the groove defined between the plurality of ribs, and the water flow and the rib can be passed through The friction acts to buffer the water flow, so that the water flow can be maintained in a relatively stable state, thereby reducing noise.

Further, a plurality of elongated ribs may extend in the circumferential direction of the return pipe 700 and a plurality of ribs may be spaced apart in the axial direction of the return pipe 700. Thus, in the process of the water flow flowing down the inner wall of the return pipe 700, the circumferentially extending ribs have a certain hindrance to the water flow, can slow the flow of the water flow, and can stabilize the water flow in a relatively stable state. This can reduce noise.

Optionally, the return pipe 700 can be a bellows, and the forming process of the bellows is simple and low in cost.

Of course, a plurality of elongated ribs may extend along the axial direction of the return pipe 700 and a plurality of ribs may be spaced apart in the circumferential direction of the return pipe 700, or a plurality of elongated ribs may be along the axis of the return pipe 700. The spiral extends, thereby also functioning to stabilize the flow of water.

In other embodiments of the invention, the flow stabilizing structure 710 can include a plurality of protrusions and/or dimples. That is, the flow stabilizing structure 710 may include only a plurality of protrusions, and the flow stabilizing structure 710 may also include only a plurality of dimples, or the steady flow structure 710 may include a plurality of protrusions and a plurality of dimples. When the water flows along the inner wall of the return pipe 700, the plurality of projections and/or pits make the inner wall of the return pipe 700 uneven, thereby also functioning to slow down and stabilize the water flow. Optionally, a plurality of protrusions and/or pits are uniformly distributed on the inner wall of the return pipe 700, and the cross sections of the plurality of protrusions may be circular, elliptical, polygonal, etc., and the cross sections of the plurality of dimples may also be It is a circle, an ellipse, a polygon, etc., but is not limited to the above shape.

It should be noted that the return pipe 700 may be a plastic member or a metal member. When the return pipe 700 is a plastic part, it can be injection molded. When the return pipe 700 is a metal piece, the return pipe 700 may be formed by casting or machined; or when the flow regulating structure 710 on the inner wall of the return pipe 700 is difficult to process, the return pipe 700 may be composed of two parts. Soldered.
