The upper and lower ends of the curtain body 10 are a water inlet end and a water outlet end, respectively, water flows in from the water inlet end of the curtain body 10 and flows out from the water outlet end, and a continuous and flowing water flow is formed between the water inlet end and the water outlet end. Compared with a static water surface, the flowing water flow has a large contact area with air, the conversion process of water from a liquid state to a gas state can be accelerated, the flowing water flow can supplement moisture in time, whether water exists on the curtain body 10 is easier to detect, the water can be supplemented in time, and the humidification effect of the wet curtain humidifier 1000 is better and quicker.

The curtain body 10 is respectively provided with an air inlet side and an air outlet side at two horizontal sides, when the wet curtain humidifier 1000 is used, air enters through the air inlet side and passes through water flow, so that part of water in the water flow is vaporized into water vapor, and the water vapor is taken out from the air outlet side, and the humidification function of the air outside the wet curtain humidifier 1000 is realized.

In the present application, the curtain 10 is a non-absorbent member and the curtain 10 is a rigid mesh.

In the prior art, the wet curtain is made of a material with a water absorption effect, such as cloth or paper, and due to the material characteristics of the cloth and the paper, after the wet curtain is used for a long time, water flow can corrode the cloth or the paper, so that the wet curtain is extremely easy to damage, and the humidification effect of the wet curtain can be greatly influenced. And because wet curtain is inside to have ponding for a long time, easily breed the bacterium, when wet curtain humidifier carries out the humidification to the air, moisture in the air can bring the bacterium of wet curtain inside into the air, can cause the influence to health after the human body inhales.

Curtain 10 in this application is the non-piece that absorbs water, when wet curtain humidifier opens, rivers flow through curtain 10 surface, take away moisture through the circulation of air and reach the purpose of humidification air, close the back at wet curtain humidifier, curtain 10 is owing to do not absorb water, through a period of ventilation, curtain 10 surface can become dry, and curtain 10 can not provide the environment for bacterial growing like this, and is lower to user's health hazard after using for a long time. The curtain body 10, as a non-absorbent member, can extend the service life of the wet curtain structure 100 and reduce the replacement cost for the user.

By arranging the curtain body 10 as the hard net, on one hand, the flow area of water flow on the surface of the curtain body 10 can be enlarged, and on the other hand, the flow time of the water flow on the curtain body 10 can be prolonged, so that more water can be taken away by air, the humidifying effect of the wet curtain humidifier 1000 is increased, the overall structural strength can be increased, the curtain body 10 is small in overall shaking when the air passes through the curtain body 10, and the noise is low.

Specifically, the curtain body 10 is at least one of a plastic member, an aluminum member, and a ceramic member. The curtain body 10 made of different materials can be processed in different manners, for example, when the curtain body 10 is made of plastic, the curtain body can be processed in an injection molding manner; when the curtain body 10 is made of aluminum, the aluminum curtain body can be processed in a casting mode; when the curtain body 10 is made of a ceramic material, the curtain body 10 may be formed by molding a blank of clay and then fired.

The curtain body 10 made of different materials has different characteristics, and can be selected according to requirements. For example, the curtain body 10 made of plastic has lower processing cost, the curtain body 10 made of aluminum and ceramic has better antibacterial effect, after long-time use, bacteria are not easy to generate on the surface of the curtain body 10, and a user is safer when using the wet curtain humidifier.

In one embodiment, the curtain 10 is a plastic member. In actual production, the curtain body 10 can be formed by injection molding or pouring, a mold is required to be produced by injection molding or pouring, the flow guide part 12 with the consistent shape can reduce the production cost of the mold, and further lower production cost is achieved when the curtain body 10 is processed, and enterprises can have larger profit margins.

The material of the curtain body 10 is not specifically limited in this application, and may be any one of Polyethylene (PE), Polypropylene (PP), Polyvinyl Chloride (PVC), Polymethyl Methacrylate (PMMA), and Polytetrafluoroethylene (PTFE).

Of course, the curtain body 10 in the present application may also be processed in other manners, for example, when the curtain body 10 includes the diversion part 12 and the connection part 11, the diversion part 12 may be processed separately and then connected to the connection part 11 by welding or the like, so that the curtain body 10 is overall in a net shape.

In some embodiments, the wet curtain structure 100 includes at least two curtains 10, and the at least two curtains 10 are arranged along the thickness direction of the curtain 10. At least two curtain bodies 10 are arranged, when air enters the wet curtain structure 100 from the air inlet side, the air firstly contacts the first curtain body 10 to take away a part of moisture on the surface of the curtain body 10, and then contacts the second curtain body 10 to further take away more moisture, so that the contact area between water flow and air can be increased, and a better air humidifying effect is realized. In practical application, the number of the curtain bodies 10 can be increased or decreased according to the requirement of the humidification degree of the environment, so as to realize more personalized air humidification effect.

In the present application, the number of the curtain bodies 10 is not limited, and two, three, four or more curtain bodies 10 may be provided.

When the curtain 10 includes at least two, the shape of each curtain 10 may be the same or different. Specifically, when the curtain bodies 10 are multiple, two adjacent curtain bodies 10 may be symmetrically disposed, so that the flow guiding direction of air may be adjusted, and the contact area between air and water may be increased.

Specifically, the wet curtain structure 100 includes at least three curtain bodies 10, and the curtain bodies 10 on both sides are symmetrically disposed with respect to the middle curtain body 10. This reduces the difficulty of assembling the wet curtain structure 100 and also accomplishes the work of assembling the wet curtain structure in reverse.

Further, two adjacent curtains 10 are spaced apart to form a water-air mixing space 18. The provision of the air-water mixing space 18 reduces wind resistance on the one hand, and allows air to flow through the wet curtain structure 100 over a larger area of the curtain body 10, increasing the contact area with water.

In some embodiments, as shown in fig. 2, the wet curtain structure 100 further comprises: a water distribution member 20 and a water collection member 30. The water distributing member 20 is connected above the curtain body 10, and the water distributing member 20 is provided with at least one water distributing hole 21 for distributing water toward the curtain body 10. The water collecting piece 30 is connected below the curtain body 10, a water collecting groove 31 used for containing water flow on the curtain body 10 is arranged on the water collecting piece 30, and a water collecting hole 32 communicated with the water collecting groove 31 is arranged on the water collecting piece 30. From this, through the distributive hole 21 on the water distribution piece 20, can make the more even inflow curtain 10 of rivers, increase the area of contact of rivers with water conservancy diversion portion 12, after rivers flow through curtain 10, get into water catch bowl 31 through water catch bowl 32, can go into water distribution piece 20 with rivers pump through the water pump to realize the circulation of rivers, reduce use cost.

In some embodiments, the water inlet end of the curtain 10 forms a drainage post 16 insertable into the water distribution aperture 21 and the water outlet end of the curtain 10 forms a drainage post 17 insertable into the water collection aperture 32. When water flows through the water diversion holes 21, due to the surface tension of water, water can form bubbles at the water diversion holes 21 to block the water flow from flowing in, and the water collection holes 32 are similar to each other, so that the liquid guide columns 16 and the water guide columns 17 are formed on the curtain body 10, the water can be prevented from forming bubbles at the water diversion holes 21 and the water collection holes 32, and the water can flow more smoothly. And the liquid guiding column 16 and the liquid guiding column 17 can provide guidance for water flow flowing into the curtain body 10 or the water collecting piece 30, increase the flow efficiency of the water flow in the wet curtain structure 100, and increase the humidifying effect of the wet curtain humidifier.

Further, when the wet curtain structure 100 includes a plurality of curtain bodies 10, the water inlet end of each curtain body 10 forms a row of liquid guiding columns 16, the water outlet end of each curtain body 10 forms a row of drainage columns 17, the water distributing member 20 is provided with a plurality of rows of water distributing holes 21, and the water collecting member 30 is provided with a plurality of rows of water collecting holes 32. Therefore, the flow efficiency of the water flow in the wet curtain structure 100 is increased, and meanwhile, the structural strength of the wet curtain structure 100 can be further increased, and the service life of the wet curtain structure 100 is prolonged.

Specifically, the curtain body 10 is connected with at least one of the water distributing member 20 and the water collecting member 30 in a snap-fit manner, so that the assembling efficiency can be improved.

In the present application, the shape of the curtain 10 can be implemented in various ways, and the following structural figures describe the structure of the curtain 10 in various embodiments.

The wet curtain structure 100 of one embodiment of the present application is described below with reference to fig. 2-8.

As shown in fig. 2-3, the upper and lower ends of the curtain body 10 are respectively a water inlet end and a water outlet end, the curtain body 10 includes a connection part 11 and a plurality of flow guiding parts 12, the plurality of flow guiding parts 12 are sequentially arranged along the horizontal direction, the connection part 11 connects the plurality of flow guiding parts 12 to make the curtain body 10 in a net shape, and the two sides of the curtain body 10 along the thickness direction are respectively an air inlet side and an air outlet side. In the example of fig. 2 and 3, the upper end of the curtain body 10 is the water inlet end, the lower end is the water outlet end, the front side is the air inlet side, and the rear side is the air outlet side.

Wherein, at least one flow guide part 12 is a wave shape extending along the up-down direction, an air passing channel 13 is defined between the adjacent flow guide parts 12, and the air passing channel 13 is used for ventilating along the thickness direction of the curtain body 10. The flow guide part 12 is formed in a wave shape extending in a winding manner, so that on one hand, the flow area of water flow on the surface of the flow guide part 12 can be increased, and on the other hand, the flow time of the water flow on the curtain body 10 can be prolonged, so that more water can be taken by air, and the humidifying effect of the wet curtain humidifier 1000 can be improved. Through setting water conservancy diversion portion 12 to a plurality of along the horizontal direction distribution, can make rivers flow area, air and rivers area of contact increase at double, through connecting into the net with a plurality of water conservancy diversion portions with the connecting portion, can increase overall structure intensity, make the air whole when passing the curtain rock for a short time, the noise is low.

Set up water conservancy diversion portion 12 to the wave form that the upper and lower direction meanders and extends in this application, water supply can flow and block less to the air in the 12 surfaces of water conservancy diversion portion, can reduce the windage, reduces wet curtain humidifier 1000's energy consumption.

As shown in fig. 3-6, in some embodiments, the flow guide 12 is a baffle 120, the baffle 120 extending through the thickness of the curtain 10. Therefore, the surface area of the guide plate 120 can be increased, water flow can flow on the surface of the guide plate 120 when flowing through the guide plate 120 to form a water film, and when air passes through the guide plate 120, the guide plate 120 with a larger area can lead the air to take away more moisture, thereby increasing the humidification efficiency of the wet curtain humidifier 1000.

It can be understood that the air flows from the air inlet side to the air outlet side, and flows generally along the thickness direction of the curtain body 10, therefore, the flow guide part 12 is configured as a flow guide plate 120 extending along the thickness direction of the curtain body 10, and the shape of the flow guide plate 120 is consistent with the air flow direction, which is beneficial to reducing the pressure loss and increasing the air supply distance. When there are a plurality of curtain bodies 10, the air passes through a plurality of curtain bodies 10, and the guide plate 120 on the curtain body 10 is beneficial to guiding the flow direction of the air flow, thereby reducing the energy consumption of wind resistance.

It should be noted that, when the wet curtain humidifier 1000 is provided with the wet curtain structure 100, the fan 500 drives air to flow through the wet curtain structure 100, so as to take away moisture on the wet curtain structure 100. Therefore, when the wet curtain structure 100 is unreasonable, the air wind resistance is high in power consumption, the structure of the flow guide part 12 is favorable for reducing the wind resistance, the fan 500 with the same power can drive more air to flow through the wet curtain structure 100, and the humidifying efficiency of the wet curtain humidifier 1000 is improved.

Specifically, when the baffle 120 extends along the thickness direction of the curtain 10, the baffle 120 may be perpendicular to the plane of the curtain 10, so that the air guiding direction of the baffle 120 flows along the direction perpendicular to the thickness direction of the curtain 10. In some schemes, when the guide plate 120 extends along the thickness direction of the curtain body 10, the guide plate 120 has a certain inclination angle with respect to the thickness direction of the curtain body 10, and when the inclination angle is not large, the functions of guiding air flow and reducing wind resistance can also be achieved.

Alternatively, when a plurality of baffles 120 are disposed on the curtain 10, the plurality of baffles 120 may all extend in a direction perpendicular to the thickness of the curtain 10, or a portion of the baffles 120 may have an oblique angle with respect to the thickness of the curtain 10 and a portion of the baffles may extend in a direction perpendicular to the thickness of the curtain 10.

In some embodiments, as shown in fig. 3, the baffle 120 has a first chamfer c1 on both the air inlet side and the air outlet side. The first chamfer c1 is formed on the air inlet side of the deflector 120, which is equivalent to the formation of a sharp edge on the air inlet side of the deflector 120, and is beneficial to splitting the air flow when facing the wind, so that the air flow flows to the air passing channel 13 from the left and right sides of the deflector 120, and the wind resistance is reduced. The first chamfer c1 is formed on the air outlet side of the guide plate 120, which is beneficial to guiding the air flows on the left and right sides of the guide plate 120 to merge along the first chamfer c1, thus reducing the disturbance of the air flow formed on the air outlet side of the guide plate 120 and reducing the wind resistance.

It should be noted that, the angles of the first chamfer c1 on the air inlet side and the air outlet side of the baffle 120 are not particularly limited, the angle of the first chamfer c1 may be 30 °, 45 ° or 60 °, the first chamfer c1 may also be a rounded corner, and different angles of the first chamfer c1 have different air guiding effects for air, and may be selected according to actual needs.

As shown in fig. 4 and 6, in some embodiments, the baffle 120 has a sheet width W along the thickness of the curtain 10, with at least some segments of the baffle 120 having a sheet width W that increases downwardly. Rivers can constantly spread when flowing from top to bottom, and what the plate width W that increases gradually can be better accepts rivers, reduces probability outside rivers spill curtain body 10, is favorable to making wet curtain humidifier 1000 inside cleaner. And after the water flow is spread, the area is increased, which is beneficial to increasing the contact area with the air and improving the humidifying effect.

As shown in fig. 3, the width W of the baffle 120 adjacent the bottom tapers as shown in fig. 6. Rivers flow from last to down along the surface of guide plate 120, through dwindling the board width W near the bottom gradually, can guide rivers, make rivers get into out the water end, prevent that rivers from spilling wet curtain structure 100, increase the cleanliness factor of wet curtain humidifier 1000 operation in-process.

In the example of fig. 6, the width W of the baffle 120 gradually increases from top to bottom, and when increasing to a maximum of W', the width W of the baffle 120 gradually decreases, thereby gradually converging the water flow.

As shown in fig. 3-4, in some embodiments, the plurality of flow-guiding portions 12 of the curtain body 10 are all wave-shaped with a uniform shape, each flow-guiding portion 12 has peaks 121 and valleys 122 alternately arranged thereon, and the plurality of flow-guiding portions 12 have peaks 121 with the same height and valleys 122 with the same height. Therefore, the wave forms of the guide parts 12 are tidy, airflow is favorably dredged, and wind resistance is further reduced. The wave connecting rib 111 is located at the position of the wave crest 121 or the wave trough 122 of the flow guiding part 12, so that the structural strength of the curtain body 10 is increased while the flowing efficiency of water flow on the curtain body 10 is not influenced, the service life of the wet curtain structure 100 is prolonged, and the use cost of a user is reduced.

For convenience of description, in the embodiment of fig. 2 to 4, the leftmost point of the waveform of the flow guide portion 12 protruding to the left is referred to as a peak 121, and the rightmost point of the waveform of the flow guide portion 12 protruding to the right is referred to as a valley 122. In fig. 4, the peaks 121 and valleys 122 of each flow guide 12 are alternately arranged. In the plurality of flow guiding parts 12, a plurality of rows of wave crests 121 and a plurality of rows of wave troughs 122 are present, the heights of the wave crests 121 in the same row are equal, the heights of the wave troughs 122 in the same row are equal, and the rows in which the wave crests 121 are located and the rows in which the wave troughs 122 are located are alternately distributed.

In some embodiments, as shown in fig. 3-4, the connecting portion 11 includes a plurality of coupling ribs 111, the coupling ribs 111 are arranged in a vertically spaced manner, the dimension of the coupling ribs 111 along the thickness direction of the curtain body 10 is a rib width V, and the rib widths V of the plurality of coupling ribs 111 gradually increase downward.

As in the example of fig. 6, on two adjacent corrugated ribs 111, the rib width of the upper corrugated rib 111 is V1, the rib width of the lower square-wave rib 111 is V2, and V2 is greater than V1. Therefore, the larger the rib width V of the most downward wave connecting rib 111 on the curtain body 10 is, the stronger the supporting function is, and the improvement of the whole bottom stability of the curtain body 10 is facilitated. And when rivers on the ripple even muscle 111 flow downwards, make the water on the ripple even muscle 111 of top most flow downwards on the ripple even muscle 111 of below, consequently the muscle width V of ripple even muscle 111 increases downwards gradually, is favorable to the rivers to form continuous cascade through a plurality of ripples even muscle 111, and the air current takes away more moisture when blowing through the cascade.

Alternatively, as shown in fig. 6, the corrugated connecting rib 111 has a second chamfer c2 on both the air intake side and the air discharge side. The second chamfer angle C2 is favorable to the rivers on the ripple even muscle 111 to smoothly flow to ripple even muscle 111 both sides along second chamfer angle C2, improves the smoothness and the continuity that rivers flow, increases rivers and adheres to the area.

As shown in fig. 3 and 4, in some embodiments, the connecting portion 11 includes a plurality of wave connecting ribs 111, the wave connecting ribs 111 are arranged in an up-down interval, each wave connecting rib 111 is connected to peaks 121 at the same height of the plurality of flow guides 12, or each wave connecting rib 111 is connected to valleys 122 at the same height of the plurality of flow guides 12. When water flows on the flow guide part 12, a larger flow area is formed on the arc surface between the wave crest 121 and the wave trough 122 in the flow guide part 12, and the wave crest 121 and the wave trough 122 mainly function in guiding and steering the water flow, so that the contact time of the water flow with air in the curtain body 10 is longer, and the wave connecting rib 111 is connected with the wave crest 121 or the wave trough 122, so that the water flow cannot be blocked. And the corrugated connecting ribs 111 are only arranged at the wave crests 121 or the wave troughs 122, when air passes through the wet curtain structure 100, the corrugated connecting ribs 111 do not influence the flow of the air, so that the wet curtain structure 100 has higher humidifying efficiency.

The wave connecting rib 111 is located at the position of the wave crest 121 or the wave trough 122 of the flow guiding part 12, so that the structural strength of the curtain body 10 can be increased while the flowing efficiency of water flow in the curtain body 10 is not influenced, the service life of the wet curtain structure 100 is further prolonged, and the use cost of a user is reduced.

As shown in fig. 3-4, in some embodiments, the connection portion 11 further includes: two vertical side plates 112, an upper connecting transverse rib 113 and a lower connecting transverse rib 114. Two vertical side plates 112 are vertically spaced apart, and a plurality of flow guides 12 are located between the two vertical side plates 112. The upper connecting transverse rib 113 is connected between the two vertical side plates 112, and the upper ends of the plurality of flow guiding parts 12 are connected with the upper connecting transverse rib 113. The lower horizontal ribs 114 are connected between the two vertical side plates 112, and the lower ends of the plurality of guide portions 12 are connected to the upper horizontal ribs 113. Therefore, the structure of the two vertical side plates 112, the upper horizontal rib 113 and the lower horizontal rib 114 can provide a frame for the wet curtain structure 100, so that the structural strength of the wet curtain structure 100 is increased, the service life of the wet curtain structure 100 is longer, and the use cost of a user is reduced.

As shown in fig. 2, when the wet curtain structure 100 includes a plurality of curtain bodies 10, the plurality of flow guiding portions 12 on each curtain body 10 are all wave-shaped, and each flow guiding portion 12 has peaks 121 and valleys 122 alternately arranged thereon. Wherein, two curtain bodies 10 are at the same height, the wave crest 121 on the guiding part 12 of one curtain body 10, the wave trough 122 on the guiding part 12 of the other curtain body 10. Therefore, the wave crests 121 and the wave troughs 122 on the two curtains 10 at the same height are correspondingly arranged to form a ring shape, so that the air flow guiding is further facilitated, and the wind resistance is reduced.

After the assembly is completed, when the air inlet side looks at the air outlet side, the wave crests 121 and the wave troughs 122 between the adjacent curtain bodies 10 are arranged oppositely, the two curtain bodies 10 arranged in the mode can form obstruction to air when passing through the wet curtain structure 100, the air rotates after passing through the first curtain body 10 and then passes through the second curtain body 10, the contact area of the air and the wet curtain structure 100 is further enlarged, and the humidifying efficiency of the wet curtain humidifier 1000 is increased.

As shown in fig. 2, 7-8, in some embodiments, the wet curtain structure 100 further comprises: a water distributing member 20 and a water collecting member 30. The water distributing member 20 is connected above the curtain body 10, and the water distributing member 20 is provided with at least one water distributing hole 21 for distributing water towards the curtain body 10. The water collecting piece 30 is connected below the curtain body 10, a water collecting groove 31 used for containing water flow on the curtain body 10 is arranged on the water collecting piece 30, and a water collecting hole 32 communicated with the water collecting groove 31 is arranged on the water collecting piece 30.

In some embodiments, the curtain 10 is snap-fit connected to at least one of the water distribution member 20 and the water collection member 30. Therefore, the wet curtain structure 100 can be detached through the buckle when needing to be cleaned or replaced, and convenience is improved.

As shown in fig. 3, 6-7, a plurality of upper fastening holes 22 are formed on the water distributing member 20, a plurality of lower fastening holes 33 are formed on the water collecting member 30, upper fastening hooks 14 and lower fastening hooks 15 are respectively formed at the upper and lower ends of the curtain body 10, the upper fastening hooks 14 are matched with the upper fastening holes 22, and the lower fastening hooks 15 are matched with the lower fastening holes 33. Therefore, the stability of the connection between the water distributing member 20 and the curtain body 10 and the stability of the connection between the water collecting member 30 and the curtain body 10 can be improved, the structural strength of the wet curtain structure 100 is further improved, the service life of the wet curtain structure 100 is prolonged, and the use cost of a user is reduced.

As shown in fig. 2-4, in some embodiments, the water entry end of the curtain 10 forms a drainage post 16 insertable into the water distribution aperture 21 and the water exit end of the curtain 10 forms a drainage post 17 insertable into the water collection aperture 32. When water flows through the water diversion holes 21, due to the surface tension of water, water can form bubbles at the water diversion holes 21 to block the water flow from flowing in, and the water collection holes 32 are similar to each other, so that the liquid guide columns 16 and the water guide columns 17 are formed on the curtain body 10, the water can be prevented from forming bubbles at the water diversion holes 21 and the water collection holes 32, and the water can flow more smoothly. And the liquid guiding column 16 and the liquid guiding column 17 can provide guidance for water flow flowing into the curtain body 10 or the water collecting member 30, increase the flow efficiency of the water flow in the wet curtain structure 100, and increase the humidifying effect of the wet curtain humidifier 1000.

Further, when the wet curtain structure 100 includes a plurality of curtain bodies 10, the water inlet end of each curtain body 10 forms a row of liquid guiding columns 16, the water outlet end of each curtain body 10 forms a row of drainage columns 17, the water distributing member 20 is provided with a plurality of rows of water distributing holes 21, and the water collecting member 30 is provided with a plurality of rows of water collecting holes 32. Therefore, the flow efficiency of the water flow in the wet curtain structure 100 is increased, and the structural strength of the wet curtain structure 100 is further increased, so that the service life of the wet curtain structure 100 is prolonged.

An alternative embodiment of the wet curtain structure 100 is described below with reference to fig. 9 and 13.

Referring to fig. 9 to 12, the curtain body 10 includes a plurality of flow guiding portions 12, the flow guiding portions 12 are sequentially arranged in an up-down direction, and water flows through the flow guiding portions 12 and flows from top to bottom. An air passing channel 13 is limited between two adjacent flow guide parts 12, and air passes through water flow through the air passing channel 13 between the two flow guide parts 12, so that the flow direction of the water flow can be guided by the flow guide parts 12, the air blowing direction can be limited, the air is fully contacted with the water flow, and the wind resistance is reduced while the humidification is ensured.

In this application, a plurality of flow guiding portions 12 are arranged in sequence along the up-down direction, and when water flows from the top to the bottom, the water is sequentially received and guided by the plurality of flow guiding portions 12. Because the curtain 10 extends from the inlet end to the outlet end, the flow does not flow vertically downward from the inlet end to the outlet end under the direct action of gravity, but rather flows sequentially through the plurality of deflectors 12. When water flows through one of the diversion parts 12, a water film is formed on the surface of the diversion part 12 under the action of hydraulic tension, and when the water flows on the diversion part 12 downwards under the action of the hydraulic tension, the water flows are spread along the diversion part 12 and are connected into a water curtain. When the water curtain flows downwards, the water curtain tends to be water column shape if the water curtain is separated from the diversion part 12 for too long time, but in the application, due to the arrangement of the diversion parts 12, the water curtain falls on the diversion part 10 below before the water column is formed, and the water flow flowing downwards from the diversion part 10 is unfolded. Therefore, the plurality of flow guide parts 12 are sequentially arranged from top to bottom in the application, so that the water curtain is formed when water flows down from the flow guide parts 12, the surface area of the water curtain is large, and the contact area of the water flow and air is large.

And each water conservancy diversion portion 12 is after receiving rivers, rivers flow along water conservancy diversion portion 12 surface, and rivers form the water film behind attaching to water conservancy diversion portion 12 surface, and when air current was through water conservancy diversion portion 12, air not only contacted with the vertical downward flowing cascade, still contacted with the water film on water conservancy diversion portion 12 surface, and air and water contact area are bigger, and this kind of wet curtain structure 100's humidification ability is stronger.

In addition, after the plurality of baffles 12 block, the flowing time of the water flow on the curtain body 10 is prolonged, the contact with the air is more abundant, the evaporation amount of the water flow in the primary circulating flow is increased, and the energy consumption can be reduced.

As shown in fig. 10 and 12, in some embodiments, the guiding portion 12 is a guiding plate 120 extending from the air inlet side to the air outlet side, and the guiding plate 120 is a long strip.

Taking the embodiment of fig. 11 and 12 as an example, the flow guide part 12 is plate-shaped, and thus may be referred to as a flow guide plate 120. The baffle 120 is long in the left-right direction, so that it is long in the left-right direction. In this scheme, the front side of the guide part 12 is the air inlet side, the rear side is the air outlet side, and the guide plate 120 is a plate body extending from front to rear. The size of the front and back direction of the guide plate 120 is much smaller than that of the left and right direction, so that the curtain body 10 is net-shaped as a whole, the curtain body 10 is thin, and the installation space can be saved.

Utilize water conservancy diversion portion 12 to form to guide plate 120 in this application, not only can increase the surface, make the water film area on water conservancy diversion portion 12 surface increase to rivers increase with air area of contact, the humidification ability is strengthened, also help prolonging the flow time of rivers on water conservancy diversion portion 12 surface moreover, make the evaporation of water more abundant, promote the vapor content who finally sees off, make the humidification effect of wet curtain humidifier more showing.

The guide plates 120 extend from the air inlet side to the air outlet side, so that the air resistance of the guide part 12 is reduced, and a longer air passing channel 13 is formed between the two guide plates 120, which is favorable for increasing the air supply distance, reducing the air pressure loss and further reducing the energy consumption.

In the solution of the present application, when the guiding portion 12 is the strip-shaped guiding plate 120, the whole curtain body 10 is in a net shape, and the direction from the air inlet side to the air outlet side is also the thickness direction of the curtain body 10. When the flow guide part 12 is the flow guide plate 120, the shape of the flow guide plate 120 may not be limited. In some schemes, the guide plate 120 is a straight plate, the guide plate 120 extends straight along the thickness direction of the curtain body 10, and the extending direction of the guide plate 120 may also form a certain included angle with the thickness direction of the curtain body 10.

In some schemes, the baffle 120 may also be an arc-shaped plate, so that the surface area of the baffle 120 is larger, which is beneficial to forming a larger water film and contacting with air. Advantageously, when the guide plate 120 is an arc-shaped plate, the middle position of the guide plate 120 protrudes downward, which is beneficial for the upper surface of the guide plate 120 to receive a certain amount of water, so that a thicker water film is formed on the upper surface of the guide plate 120.

In some alternatives, a portion of the baffle 120 extends in a downward curve in a direction toward the air-out side, and a portion of the baffle 120 extends in an upward curve in a direction toward the air-out side.

Of course, in other embodiments of the present application, the flow guide part 12 may not be provided with the flow guide plate 120, or may be at least partially formed into a rod shape (such as a round rod, a square rod, etc.), and the rod-shaped flow guide part 12 may also reduce the water flow speed, so that the water flow flowing downwards forms a water curtain. In contrast, the deflector 120 formed by the deflector 12 has a large surface area and a longer water flow time.

In some embodiments, at least one of the flow-directing portions 12 is a baffle 120, and the flow-directing portions 12 may be all baffles 120 or may be partially baffles 120.

Specifically, the baffle 120 may be a first baffle 1201 extending downward in a direction from the air inlet side to the air outlet side, and the baffle 120 may also be a second baffle 1202 extending downward in a direction from the air outlet side to the air inlet side. As shown in fig. 11, the plurality of baffles 120, a portion of the baffles 120 are first baffles 1201 and a portion of the baffles 120 are second baffles 1202.

Taking the orientation shown in fig. 11 as an example, the first baffle 1201 extends downward in the direction from the air intake side to the air exhaust side, so that the water falling on the first baffle 1201 can be directed downward and rearward by the first baffle 1201. The second baffle 1202 extends downward from the air outlet side to the air inlet side so that water falling on the second baffle 1202 can be directed forward and downward through the second baffle 1202. Thus, the baffle 120 can direct water in different directions as desired. Since the air is also guided by the baffle 120 when flowing through the wind channel 13, the air flow can be directed in different directions as desired. So set up, be convenient for prolong the flow path of rivers and air as required, make rivers and air contact more abundant.

Specifically, the plurality of flow guiding portions 12 are a plurality of flow guiding plates 120, the plurality of flow guiding plates 120 include first flow guiding plates 1201 and second flow guiding plates 1202 which are alternately distributed along the up-down direction, the first flow guiding plates 1201 extend downwards from the air inlet side to the air outlet side, and the second flow guiding plates 1202 extend downwards from the air outlet side to the air inlet side.

Thus, the curtain 10 as a whole appears to form a vertical row of first baffles 1201 and a vertical row of second baffles 1202, with the two vertical rows of baffles 120 being arranged in a crossed configuration. Thus, when air enters from the air inlet side, if the air meets a vertical row of first deflectors 1201, the air is guided downwards by the first deflectors 1201 in the vertical row when flowing towards the air outlet side. When air enters from the air inlet side, if the air meets a vertical row of second guide plates 1202, the air is guided upwards under the guide of the vertical row of second guide plates 1202 when flowing towards the air outlet side, so that the air flows from the air inlet side to the air outlet side integrally, and is dredged by the plurality of guide plates 120 when flowing, and the wind resistance is reduced.

When the water flows down to the guide plate 120, the flow path of the water flow is generally wave-shaped, long and flows downward as a whole for final collection, guided by the alternating first guide plate 1201 and second guide plate 1202.

Further, as shown in fig. 10, the upper end of the second baffle 1202 is closer to the air outlet side than the lower end of the upper first baffle 1201. Therefore, when water flows through the first guide plate 1201 and falls to the second guide plate 1202, the second guide plate 1202 can guide the water flow towards the upper end of the first guide plate 1201 as far as possible, and the possibility that the water flow overflows from the air outlet side of the second guide plate 1202 is reduced, so that on one hand, the flow path of the water flow can be prolonged, on the other hand, the outward overflow probability of the wet curtain structure 100 is reduced, and the internal cleanliness of the wet curtain humidifier is improved.

Further, as shown in fig. 10, the upper end of the first baffle 1201 is closer to the air intake side than the lower end of the second baffle 1202 above. Here, when water flows through the second flow guiding plate 1202 and falls to the first flow guiding plate 1201, the first flow guiding plate 1201 can guide the water flow towards the upper end of the second flow guiding plate 1202 as far as possible, so as to reduce the possibility that the water flow overflows from the first flow guiding plate 1201 on the air inlet side, thereby on one hand, the flow path of the water flow can be extended, on the other hand, the probability of outward overflow of the wet curtain structure 100 is reduced, and the internal cleanliness of the wet curtain humidifier is improved.

In some embodiments, as shown in FIG. 10, the baffle 120 has a width W along the thickness of the curtain 10. The plate width of the first deflector 1201 is W1, the plate width of the second deflector 1202 is W2, and the plate width W1 of the first deflector 1201 is not equal to the plate width W2 of the second deflector 1202.

For example, in fig. 10 there are three curtains 10, two side curtains 10, with the first deflector 1201 having a sheet width W1 greater than the sheet width W2 of the second deflector 1202. In the center curtain 10, the first deflector 1201 has a sheet width W1 that is less than the sheet width W2 of the second deflector 1202.

When the width W1 of the first baffle 1201 is larger, the guiding effect of the first baffle 1201 on the curtain 10 is stronger, and the width W2 of the second baffle 1202 is smaller, so that the insertion depth of the second baffle 1202 in the first baffle 1201 is smaller, and thus the gap between two adjacent first baffles 1201 is larger, which is convenient for the air flow to flow. And because the direction of first guide plate 1201 and second guide plate 1202 is certain contained angle, the wind of deriving between first guide plate 1201 meets with the water film on the second guide plate 1202 almost perpendicularly like this, can make the air blow in fully contact in the water film, further improves the humidification effect.

Similarly, when the width W2 of the second baffle 1202 is larger in the curtain 10, the guiding effect of the second baffle 1202 is stronger in the curtain 10, and the width W1 of the first baffle 1201 is smaller, so that the insertion depth of the first baffle 1201 in the second baffle 1202 is smaller, and thus the gap between two adjacent second baffles 1202 is larger, thereby facilitating the air flow. And because the second guide plate 1202 and the direction of first guide plate 1201 are certain contained angle, the wind that derives from between first guide plate 1201 meets with the water film on the second guide plate 1202 almost perpendicularly like this, can make the air blow in the water film and fully contact, further improves the humidification effect.

Optionally, at least a portion of the baffles 120 taper in plate thickness d in the downward direction. It will be appreciated that the water flow generally falls to the upper end of the baffle 120 and then flows down the baffle 120 as it flows over the baffle 120. The thickness d of the upper end of the guide plate 120 is large, so that the impact force of falling of large water flow can be borne, when the water flow on the guide plate 120 flows downwards stably, the impact on the lower end of the guide plate 120 is small, the thickness d of the plate body of the guide plate 120 is made to be downwards reduced gradually, the weight is favorably reduced, and more air is made to flow. When the thinner end of the baffle 120 is located on the windward side, the thickness d is smaller, which is easy to split the airflow, so that the airflow flows from the upper side and the lower side of the baffle 120. When the thinner end of the air deflector 120 is located at the air outlet side, the thickness of the plate body is gradually reduced, which is beneficial to the air flow confluence at the upper side and the lower side of the air deflector 120. Therefore, the wind resistance is favorably reduced, and the loss is reduced.

In some embodiments, as shown in fig. 11 and 12, at least one of the guiding portions 12 is provided with a blocking rib 1203, and the blocking rib 1203 extends along a direction from the air inlet side to the air outlet side. After the blocking ribs 1203 are arranged, water flow on the flow guide part 12 is favorably dispersed by the blocking ribs 1203 instead of being concentrated at one position and flowing downwards to form a water column, so that the contact area of water and air is favorably increased.

Specifically, the plurality of ribs 1203 are provided, and the plurality of ribs 1203 are distributed at intervals along the length direction of the flow guide portion 12. After the blocking ribs 1203 are arranged, water can be distributed on the same guide plate 120 along the length direction, the contact area of the water and the air is further increased, and therefore the humidifying effect of the wet curtain humidifier is improved.

In some embodiments, as shown in fig. 12, the flow guide part 12 includes a first flow guide plate 1201 and a second flow guide plate 1202, and a plurality of ribs 1203 are respectively disposed on the first flow guide plate 1201 and the second flow guide plate 1202. The plurality of ribs 1203 on the first baffle 1201 are spaced apart along the length, and the plurality of ribs 1203 on the second baffle 1202 are spaced apart along the length.

In some embodiments, as shown in fig. 11 and 13, a plurality of diversion ribs 1204 are disposed on the uppermost diversion part 12, one end of the plurality of diversion ribs 1204 is disposed adjacent to the water inlet end of the curtain body 10, and the other ends of the plurality of diversion ribs 1204 are spaced apart along the length direction of the diversion part 12, so as to separate the water flow. From the rivers that intake the end and flow in, can form stranded rivers under reposition of redundant personnel muscle 1204's effect, rivers not only disperse along length direction on water conservancy diversion portion 12 like this, and the rivers that disperse moreover are when the downward flow even flow roughly, are favorable to dispersing rivers and form the cascade through water conservancy diversion portion 12, are favorable to further increasing the area of contact of water with the air like this to increase the humidification effect of wet curtain humidifier.

Specifically, the water inlet end of the curtain body 10 is formed into a plurality of liquid guiding columns 16, the plurality of liquid guiding columns 16 are distributed at intervals along the length direction of the flow guiding part 12, and the flow dividing ribs 1204 are in a plurality of groups and are respectively distributed adjacent to the plurality of liquid guiding columns 16. The water flows to the flow guide plate 120 through the liquid guide column 16 and is divided into a plurality of water flows by the plurality of flow dividing ribs 1204, so that the humidifying effect of the wet curtain humidifier is stronger.

As shown in fig. 13, each fluid guiding column 16 is provided with a set of flow dividing ribs 1204, one end of each of the flow dividing ribs 1204 in the same set is disposed around the fluid guiding column 16, and the other end of each of the flow dividing ribs 1204 in the same set is spaced apart along the length direction of the fluid guiding portion 12. Alternatively, in the same set of flow-dividing ribs 1204, they are symmetrically arranged, so that the water flow is uniformly distributed. Further alternatively, there are two diversion ribs 1204 connected, and the connected diversion rib 1204 is located above the diversion rib 1204, so as to block the water flow from flowing upwards and overflowing.

In some embodiments, as shown in fig. 10 and 11, the curtain 10 includes: the connecting part 11 is used for connecting the plurality of flow guide parts 12, so that the curtain body 10 forms a whole and is convenient to assemble.

Specifically, the connection portion 11 includes: two vertical side plates 112, two vertical side plates 112 are vertically spaced apart, and a plurality of guiding parts 12 are connected between the two vertical side plates 112. The provision of the vertical side plate 112 can prevent water from overflowing from both side ends of the guide plate 120, resulting in waste of water.

Of course, the connecting portion 11 may have other structures, for example, may include at least one vertical rib, and the vertical rib is disposed on the plurality of flow guiding portions 12.

Yet another embodiment of a wet curtain structure 100 is described below with reference to fig. 14-19.

Referring to fig. 16 and 17, the curtain body 10 includes a connection portion 11 and a plurality of flow guide portions 12, the plurality of flow guide portions 12 are sequentially arranged in an up-down direction, an air passage 13 is provided between two adjacent flow guide portions 12, and the connection portion 11 is connected to the plurality of flow guide portions 12. By arranging the water receiving groove 19 on at least one flow guide part 12, and opening the water receiving groove 19 upwards, the water receiving groove 19 has a certain water storage amount. When water falls on the diversion part 12, the water flow can flow into the water receiving tank 19 along the surface of the diversion part 12. The arrangement of the water receiving groove 19 can increase the surface area of the flow guide part 12, and the water receiving groove 19 can store a certain amount of water, so that the curtain body 10 can prolong the humidifying function by using the water stored in the water receiving groove 19 if the water source is insufficient. When the water in the water receiving tank 19 is full, the water receiving tank 19 will overflow continuously when receiving water, and the overflow flows downwards to the flow guide part 12 or other parts below.

In the present embodiment, each flow guiding portion 12 is preferably elongated, and the length direction of the flow guiding portion 12 is identical to the width direction of the curtain body 10.

Taking the scheme of fig. 17 as an example, the deflector 12 is long in the left-right direction, and thus it is long in the left-right direction. In the scheme, the front side of the diversion part 12 is an air inlet side, the rear side is an air outlet side, or the front side of the curtain body 10 is the air inlet side, the rear side of the curtain body 10 is the air outlet side, the air passing channel 13 on the curtain body 10 is communicated along the front-rear direction, and air can be blown from the front side to the rear side.

The size of the flow guide part 12 in the front-back direction is much smaller than that in the left-right direction, so that the curtain body 10 is net-shaped as a whole, the curtain body 10 is thin, and the installation space can be saved.

When the guiding portion 12 is a long strip, the guiding portion 12 may be a straight line, and the guiding portion 12 may also be a curved line. When the plurality of flow guiding portions 12 are all long strips, the plurality of flow guiding portions 12 may be all linear, or the plurality of flow guiding portions 12 may be all curved. In some schemes, when the curve shape is reasonably set, even the straight line part in the plurality of flow guide parts 12 can be set into the curve shape, for example, the uppermost flow guide part 12 can be set into the wave line shape, and the lower flow guide part 12 is straight line.

The vertical cross-sectional shape of each flow guide portion 12 may be a plane-symmetrical shape or may not be a plane-symmetrical shape. Each flow guide part 12 has a vertical cross-sectional shape which may be a regular shape or an irregular shape. Not intended to be limiting. In the example of fig. 17 and 19, each flow guide part 12 is in a plane-symmetrical shape, the flow guide parts 12 are symmetrical with respect to the same vertical plane, the shape of two adjacent flow guide parts 12 is the same, the size of the lower flow guide part 12 of the two adjacent flow guide parts 12 is larger than that of the upper flow guide part 12, each curtain body 10 is approximately in the shape of an isosceles triangle when viewed from the side, and the openings of the flow guide parts 12 are arranged to increase from top to bottom.

In some embodiments, as shown in fig. 17 and 19, the curtain 10 has a median reference plane S. To facilitate understanding of the median reference plane S, the median reference plane S is defined herein as follows: the side of each flow guide part 12 closest to the air inlet side is an upstream side aa, the side of each flow guide part 12 closest to the air outlet side is a downstream side bb, the distance between the upstream side aa and the middle reference surface S is an upstream distance La, the distance between the downstream side bb and the middle reference surface S is a downstream distance Lb, and the upstream distance La is equal to the downstream distance Lb.

That is, each of the guide portions 12 has an upstream side aa and a downstream side bb, and a reference side is equidistant from the upstream side aa and the downstream side bb in the thickness direction of the curtain body 10. The reference plane constructed by the reference edges of the plurality of flow guiding parts 12 on the same curtain body 10 is the median reference plane S.

Wherein, the curtain body 10 has at least two diversion parts 12, and the upstream distance La of the diversion part 12 below is greater than the upstream distance La of the diversion part 12 above.

Taking fig. 19 as an example, in the curtain body 10 of the embodiment of fig. 19, there are two flow guides 12, the upstream distance of the upper flow guide 12 is La1, the upstream distance of the lower flow guide 12 is La2, and La1< La 2. Since La is Lb on the same flow guide portion 12, the downstream distance Lb of the lower flow guide portion 12 is greater than the downstream distance Lb of the upper flow guide portion 12 on the two flow guide portions 12. In this way, if the thickness direction of the curtain body 10 is defined as the width of the guide portion 12, the width of the two guide portions 12 increases downward.

It will be appreciated that the surface tension effect on the deflector 12 may be progressively spread as the water flows downwardly. The lower deflector 12 is wider than the upper deflector 12, so that the diffused water flow can flow on the surface of the deflector 12 for a longer time, thereby prolonging the water flow time and increasing the contact area with air.

In some solutions, the water flow is blocked by the plurality of diversion parts 12 when flowing downwards, the impact force is gradually consumed, and the flow rate of the water flow may gradually decrease, so that the more the water amount adheres to the surface of the diversion part 12. Therefore, by increasing the width of the diversion part 12, the possibility that more water can flow on the surface of the diversion part 12 instead of being splashed outside the curtain body 10 due to everywhere attachment is facilitated, and the water flow inside the curtain body 10 can be kept to flow without flowing outside.

Specifically, all the diversion parts 12 on the curtain body 10 are provided with water receiving grooves 19 with upward openings, and the upstream distances La of the diversion parts 12 gradually increase downwards.

Through setting up the curtain 10 of taking a plurality of water conservancy diversion portions 12, a plurality of water conservancy diversion portions 12 are arranged along upper and lower direction in proper order, and every water conservancy diversion portion 12 all is formed with the water receiving tank 19 that open side up, can follow curtain 10 top cloth liquid like this when distributing liquid, and liquid can flow each water receiving tank 19 in proper order from the top down. Through set up between two adjacent water conservancy diversion portions 12 and cross wind passageway 13, the air current can pass curtain 10 from passing wind passageway 13, and the air current can flow through water receiving tank 19, lets impurity or harmful gas etc. in the liquid can the adsorbed gas current.

The upstream distance La of the plurality of flow guiding parts 12 is gradually increased downwards, so that the water containing amount of the plurality of flow guiding parts 12 is gradually increased downwards. The water flow time can be further prolonged, and the water flow can be better humidified after being spread.

Further, the middle reference plane S is a vertical plane, and the flow guide portions 12 are symmetrically arranged with respect to the middle reference plane S. The processing is very convenient.

When the median reference plane S is a vertical plane, and the upstream distance La of the lower deflector 12 is greater than the upstream distance La of the upper deflector 12, the horizontal projection area of the upper deflector 12 is completely located within the horizontal projection area of the lower deflector 12.

In two of the guide parts 12 of the curtain body 10, the horizontal projection area of the upper guide part 12 is smaller than the opening area of the lower guide part 12, and when the upper guide part 12 is filled with liquid, the liquid can overflow from the edge of the upper guide part 12 and flow downwards into the lower guide part 12, so that the wet curtain forming effect of the curtain body 10 is better.

So be provided with the walking route that does benefit to extension liquid, increase the distribution area of liquid to increase the area of contact of liquid and air current, improve the humidification effect. Such wet curtain structure 100 may be used in any manner, for example, the wet curtain structure 100 may be wetted only once, or the wet curtain structure 100 may be wetted intermittently. Of course, the wet curtain structure 100 may be continuously liquid-distributing, with the flowing liquid being in sufficient contact with the air flow. The horizontal projection area of the upper flow guide part 12 is smaller than that of the lower flow guide part 12, so that the liquid flow velocity is reduced, the contact time of liquid and air flow is prolonged, and the filtering effect is further improved.

In some embodiments, a plurality of flow guiding parts 12 form a laminated structure on the curtain body 10, another flow guiding part 12 is arranged right below each flow guiding part 12, liquid overflowing from each flow guiding part 12 correspondingly flows into the water receiving tank 19 of the flow guiding part 12 below the flow guiding part, the liquid can flow through all the flow guiding parts 12 arranged in sequence from top to bottom, and a coherent and dense wet curtain can be formed while the liquid flow path is prolonged.

Therefore, the diversion part 12 can be filled with overflowed liquid and can flow into the water receiving grooves 19 of the diversion part 12 below the diversion part, so that each water receiving groove 19 can be filled with liquid when the liquid distribution amount is enough, and the liquid can uniformly flow all the water receiving grooves 19. Therefore, the contact area of the liquid and the airflow can be further increased, and the filtering effect on the airflow is improved.

In the present embodiment, the overall shape of the curtain 10 generally conforms to the median reference plane S. When the median reference plane S is a flat plane, the curtain 10 is generally like a straight netting. When the median reference plane S is a curved plane, the curtain body 10 is generally similar to a curved lath. In the present application, the shape of the median reference plane S is not limited, and thus the overall shape of the curtain body 10 is not limited.

In some embodiments, the guiding portion 12 includes two fins 125 in a pair, the lower ends of the two fins 125 are connected, the two fins 125 extend upward in a direction away from each other, and the water receiving groove 19 is formed between the two fins 125.

The flow guide part 12 is formed by the two fin plates 125, and the flow guide part 12 is simple in structure and low in processing difficulty. And two fin 125 are in the setting of extending downwards towards each other's orientation, and the upper surface of fin 125 is used for splendid attire liquid, and the lower surface of fin 125 can guide the air current flow direction, can reduce the windage like this when guaranteeing gas-liquid contact.

For example, as the air flow passes through the curtain 10, the air flow is directed downwardly by the lower surface of the fin 125 in the direction of the air flow, and then upwardly by the lower surface of the fin 125 after passing through the air passage 13. The airflow flowing to the air passage 13 is extruded downwards through the lower surface of the fin 125, so that the flow speed can be increased, and the airflow can be guided to the air passage 13, thereby being beneficial to the airflow passing through the air passage 13 and reducing the wind resistance. After passing through the air passage 13, the air flow is guided by the lower surface of the fin 125 to spread out, thereby reducing the air pressure of the wet curtain structure 100 at the air outlet end and improving the air flow passing capacity.

Specifically, in at least two pairs of fins 125 on the same curtain 10, the upper distance l1 between the upper two fins 125 is smaller than the upper distance l2 between the lower two fins 125. The fin 125 is disposed such that the opening area of the water receiving groove 19 of at least two diversion parts 12 is increased from the lower side to the upper side.

Specifically, as shown in fig. 18 and 19, the fins 125 may be straight plates or bent plates, and the two fins 125 in a pair may or may not have a plane-symmetric structure.

In the example shown in fig. 19, both fins 125 are straight plates, and both fins 125 are "V". In some examples, both fins 125 are bent plates, and both fins 125 may be "U".

When the diversion part 12 includes two paired fins 125, the water receiving tank 19 is formed between the two fins 125, and the upper surface of the two fins 125 is the bottom wall of the water receiving tank 19.

In the above embodiment, after the upper water receiving tank 19 is filled with liquid, the liquid may overflow from the upper end of the fin 125 and flow into the lower diversion part 12. It will be appreciated that some of the liquid spilled over will flow straight down in the direction of gravity and some will flow down the lower surface of the fin 125. When the distance between the upper ends of the upper two fins 125 is smaller than the distance between the upper ends of the lower two fins 125, the liquid flowing down in a straight line along the gravity direction flows into the water receiving tank 19 formed by the lower two fins 125, and the liquid is prevented from overflowing and splashing.

Further, the lower surfaces of the two fins 125 extend downward in the direction toward each other, which is not only beneficial to guiding the airflow, but also beneficial to guiding the liquid attached to the lower surfaces of the fins 125 downward, and beneficial to smooth flow of water. And so configured, the lower surface of the fin 125 can be attached with a larger amount of liquid, thereby increasing the contact area between the liquid and the air flow.

In some embodiments, as shown in fig. 19, the lower surface of the fin plate 125 is a smooth surface, further facilitating the flow of liquid along the lower surface of the fin plate 125.

In some embodiments, when the fins 125 are straight, the angle between each fin 125 and the horizontal plane may be 15 ° -60 °, for example, the angle between the fin 125 and the horizontal plane may be 15 °, 30 °, 45 °, 55 °, and the like.

In some embodiments of the present application, as shown in fig. 19, each fin 125 has a plate body thickness k that gradually increases in a downward direction. So set up, fin 125 forms to be thick about the plate body thin, and the structural stability and the bearing capacity of water conservancy diversion portion 12 can be strengthened to the lower extreme thick, and the material reduce cost can be practiced thrift to the upper end relatively thinner.

Specifically, as shown in fig. 19, the edge of each fin 125 is provided with a chamfer c to guide the flow of water. After the guiding part 12 is filled with liquid, the liquid can smoothly flow out from the upper edge of the fin 125 and then flow downward, which is beneficial for the fluid to flow on the surface of the guiding part 12, further prolongs the flow path of the liquid, and increases the contact area and the contact time of the liquid and the gas. And because liquid flows downwards from the upper end edge of fin 125, form fillet c with the edge, reduce the water flow resistance, reduce the condition that liquid splashes when meeting the resistance moreover, make things convenient for liquid to collect.

In some embodiments, as shown in fig. 18 and 19, the connecting portion 11 includes a connecting plate 116, the connecting plate 116 is connected between two adjacent guiding portions 12, the two fins 125 in pairs are connected to two opposite sides of the connecting plate 116, and the water receiving slot 19 is divided by the connecting plate 116 into an upstream slot 191 adjacent to the air inlet side and a downstream slot 192 adjacent to the air outlet side.

Such an arrangement may further enhance the structural strength of the curtain 10, and may increase the contact area between the air flow and the liquid when the liquid is adhered or flowed on the surface of the connecting plate 116.

Specifically, the connecting plate 116 is arranged so that when the upper diversion part 12 is filled with liquid and overflows to flow downwards, the liquid can flow downwards along the surface of the connecting plate 116, and a layer of water curtain is formed on the surface of the connecting plate 116, so that the contact area between the air flow and the liquid can be increased. And the surface area of the connection plate 116 is large and the contact area is also large.

Specifically, the air passage 13 includes a plurality of air holes 131, a row of air holes 131 is provided on the connecting plate 116 between two adjacent flow guiding portions 12, the same row of air holes 131 is spaced apart, and a reinforcing convex column 117 is provided between the two air holes 131 on the connecting plate 116. This can further improve the structural strength of the curtain 10. And the air channel 13 is divided into a plurality of air holes 131, which can also dredge and disperse the air flow, so that the air flow can be dispersed and contacted with the diversion part 12 with larger area.

The enhancement projection 117 of vertical setting plays the supporting role on the one hand, improves curtain 10 overall structure intensity, and the enhancement projection 117 of the vertical setting of on the other hand still plays the drainage effect, makes the liquid that top water conservancy diversion portion 12 flows out can follow enhancement projection 117 and flow diversion portion 12 downwards, is favorable to the smooth-going flow of water.

In the solution of the present application, the shape of the air passing hole 131 is not specifically limited, and may be a circular hole, an elliptical hole, or a square hole. In a specific embodiment, the air passing holes 131 are arranged in a long strip shape, as shown in fig. 18, the air passing holes 131 in a long strip shape are arranged on the connecting plate 116 at intervals, the air passing holes 131 are arranged between the two reinforcing convex columns 117, and the ventilation area of the air passing holes 131 in a long strip shape is relatively large, the wind resistance is small, and the processing is easy.

Further, the plate thickness e of the connecting plate 116 between two adjacent flow guiding parts 12 is gradually reduced upwards. This causes water on the surface of web 116 to flow in a downward direction in an inclined manner, which facilitates the attachment of water on the surface of web 116 to form a water film, and allows air flowing therethrough to absorb moisture while blowing through web 116.

In some embodiments, the connection portion 11 further includes: two vertical side plates 112, two vertical side plates 112 are vertically arranged at intervals, and a plurality of flow guiding parts 12 are connected between the two vertical side plates 112.

Alternatively, as shown in fig. 19, the plate body width g of the two vertical side plates 112 gradually decreases upward, which is equivalent to that the two vertical side plates 112 can be isosceles trapezoid plates respectively. Therefore, the width of the guide part 12 can be consistent with that of the guide part, the appearance is attractive, and the reverse assembly can be prevented during the assembly.

In some embodiments, as shown in fig. 14 and 16, when there are at least three curtain bodies 10, the intermediate position of the curtain body 10 is greater in the direction dimension U1 from the air inlet side to the air outlet side than in the direction dimension U2 from the air inlet side to the air outlet side of the outermost curtain body 10. The intermediate curtain 10 is generally heavier as the intermediate curtain 10 occupies a larger volume. This wet curtain structure 100 is favorable to maintaining structural stability, makes wet curtain structure 100 focus more steady, is difficult for empting.

The direction from the air inlet side to the air outlet side is taken as the thickness direction of the curtain body 10. When the curtain 10 is a uniform thickness net, U1 and U2 are the overall thickness of different curtains 10. When the curtain 10 is a net body with different thicknesses, U1 and U2 are the thicknesses of different curtains 10 at the same height.

In some embodiments, as shown in fig. 14 and 16, the number of the curtains 10 is three, and the volume of the water receiving groove 19 of the middle curtain 10 is larger than that of the water receiving grooves 19 of the two side curtains 10 at the same height. By means of the arrangement, the middle curtain body 10 is enabled to have large liquid holding capacity, the humidifying effect is guaranteed, the liquid holding capacity of the two side curtain bodies 10 is small, and the splashing amount of the liquid to the periphery is reduced.

Further, when the guiding portion 12 includes two fins 125 in a pair, the two fins 125 extend upward in a direction away from each other, and an included angle α 1 of the fin 125 of the curtain body 10 at the middle position with respect to the vertical plane is larger than an included angle α 2 of the fin 125 of the outermost curtain body 10 with respect to the vertical plane.

It will be appreciated that two fins 125 are attached to opposite sides of the web 116 and that the catch basin 19 is divided by the web 116 into an upstream basin 191 adjacent the inlet side and a downstream basin 192 adjacent the outlet side. The angle α 1 of the fins 125 with respect to the vertical plane substantially determines the size of the upstream and

downstream slots

191, 192 and therefore of the drip-receiving channel 19. Therefore, the design of the included angle is beneficial to the larger water receiving amount of the curtain body 10 at the middle position, stable center of gravity and strong humidifying capability.

More specifically, the air passages 13 of two adjacent curtains 10 are partially staggered. For example, in fig. 15, each curtain 10 is provided with a plurality of air passing holes 131. The air holes 131 on two adjacent curtain bodies 10 are partially staggered, and partially opposite to each other in the thickness direction of the curtain body 10.

For example, at the dashed box shown in the upper right corner of the wet curtain structure 100 of fig. 15, the front curtain 10 has an air passage hole 131. In the front view direction, the air passing holes (here, 131 ') on the rear curtain body 10 can be seen from the air passing holes 131, and the reinforcing protrusions (here, 117') on the rear curtain body 10 can be seen from the air passing holes 131, namely, on the front curtain body 10 and the rear curtain body 10, a part of the air passing holes 131 are opposite along the thickness direction of the curtain body 10, and a part of the air passing holes 131 are staggered along the thickness direction of the curtain body 10.

With such an arrangement, the portion opposite to the air passing hole 131 helps to reduce wind resistance, so that the air flow can smoothly flow through the plurality of curtains 10. The staggered part of the air passing holes 131, that is, the part of the air blown from the front air passing hole 131 is blocked by the reinforcing protrusion 117 ', and can be guided to the left and right by the reinforcing protrusion 117', so that the airflow flows through more surfaces of the flow guide part 12, and the contact area with the water flow is increased.

As shown in fig. 14, 16, in some embodiments, the wet curtain structure 100 further comprises: a water distributing member 20 and a water collecting member 30. When the wet curtain structure 100 includes a plurality of curtain bodies 10, a row of liquid guiding columns 16 is formed at the water inlet end of each curtain body 10, a row of drainage columns 17 is formed at the water outlet end of each curtain body 10, a plurality of rows of water distributing holes 21 are correspondingly formed on the water distributing member 20, and a plurality of rows of water collecting holes 32 are correspondingly formed on the water collecting member 30. Therefore, the flow efficiency of the water flow in the wet curtain structure 100 is increased, and the structural strength of the wet curtain structure 100 is further increased, so that the service life of the wet curtain structure 100 is prolonged.
