Referring to fig. 1, fig. 1 shows a schematic view of a wet curtain assembly according to an embodiment of the present application. The humidifier (not shown) provided by an embodiment of the present application includes an air duct assembly, a wet curtain assembly 100, a water pump, etc., the wet curtain assembly 100 is disposed at an air outlet of the air duct assembly, and the water pump is connected with the wet curtain assembly 100 for supplying water to the wet curtain assembly 100.

Thus, in the working process of the humidifier, the water pump pumps the water in the water tank into the wet curtain assembly 100, the air flow generated by the air duct assembly enters the wet curtain assembly 100 at the outlet of the air duct assembly, and the water evaporated from the wet curtain assembly 100 is carried and flows out of the wet curtain 60, so that the humidity of the environment is improved.

It should be noted that the specific structures of the components such as the air duct assembly and the water pump do not belong to the main application point of the present application, so the detailed description is omitted herein, and the air duct assembly and the water pump with different structures can be selected as required.

With continued reference to fig. 1, the wet curtain assembly 100 includes a wet curtain base 20, a liquid distribution unit 40, and a wet curtain 60. The wet curtain base 20 is a hollow shell-like structure and comprises a base bottom wall and base side walls formed by extending from the edge of the base bottom wall towards the same direction. In the following examples, the height direction of the wet curtain base 20 is defined as a first direction (i.e. Z direction in fig. 1), the length direction of the wet curtain base 20 is defined as a second direction (i.e. X direction in fig. 1), the width direction of the wet curtain base 20 is defined as a third direction (i.e. Y direction in fig. 1), and the first direction, the second direction and the third direction intersect each other two by two.

Further, an evaporation port 21 communicating with the external environment is formed on one side of the base side wall in the third direction, an insertion port communicating with the evaporation port 21 is formed on one side of the base side wall in the second direction, the wet curtain 60 can be installed in the wet curtain base 20 through the insertion port and is exposed to the external environment through the evaporation port 21, and air flow formed by the air duct assembly can flow through the evaporation port 21.

The cloth liquid unit 40 is mounted to an end of the wet curtain base 20 remote from the bottom wall of the wet curtain 60 in the first direction at the top of the wet curtain base 20, and a mounting chamber for accommodating the wet curtain 60 is defined between the wet curtain base 20 and the cloth liquid unit 40. The liquid distribution unit 40 forms the mounting groove 41 that has a groove diapire on the surface of one side of base diapire dorsad, and water injection hole 412 has been seted up to one side that the tank bottom wall of mounting groove 41 kept away from the installing port in the third direction, and a plurality of apopores 414 have been seted up to one side that the tank bottom wall of mounting groove 41 is close to the installing port in the third direction, and all apopores 414 interval are arranged, and water pump accessible water injection hole 412 is with water injection in the mounting groove 41, and water in the mounting groove 41 flows through apopore 414.

The wet curtain 60 has a substantially rectangular parallelepiped structure, is inserted into the wet curtain base 20 from an insertion opening of the wet curtain base 20 in the second direction, is located in the installation chamber, and extends in the second direction along the longitudinal direction of the wet curtain 60, and extends in the first direction along the height direction of the wet curtain 60, and extends in the third direction along the thickness direction of the wet curtain 60. The wet curtain 60 is located at one side of the liquid distribution unit 40 in the first direction and communicates with the drain hole 414 of the liquid distribution unit 40, so that water flowing out of the drain hole 414 flows into the wet curtain 60 to distribute liquid.

In the working process of the humidifier, one end of the wet curtain 60, which is communicated with the water outlet 414 in the first direction, receives water, and the water is spread and spread to the whole wet curtain 60, so that the evaporation efficiency of water is improved, and the humidifying effect is enhanced. The water body can be transported along the gaps such as capillary holes in the wet curtain 60 or can flow and be transported along the surface of the wet curtain 60 under the action of gravity.

As described in the background section, the conventional wet curtain 60 is prone to uneven wetting, thereby affecting the amount of humidification of the wet curtain assembly 100 and thus the use experience of the humidifier. The applicant found through studies that the above problem is caused mainly by the fact that the drain hole 414 of the conventional liquid distribution unit 40 is generally circular with a smaller diameter, and surface tension is easily generated during the process of flowing water in the installation groove 41 into the wet curtain 60 through the drain hole 414, so that the water forming liquid seals the drain hole 414, and thus the drain is uneven, and finally the wet curtain 60 is uneven.

In view of the above, referring to fig. 2, fig. 2 is a bottom view of a liquid distribution unit according to an embodiment of the application. Compared with the round small holes in the prior art, the water outlet 414 formed on the liquid distribution unit 40 is polygonal with edges, so that the situation that the water outlet 414 is in liquid sealing can be effectively reduced, water in the mounting groove 41 can smoothly flow out through each water outlet 414, the water in the liquid distribution unit 40 can uniformly and smoothly flow into the wet curtain 60, the phenomenon that the wet curtain 60 is non-uniformly wetted is effectively prevented, a good humidifying effect is further ensured, and the use experience of the humidifier provided with the wet curtain assembly 100 is improved.

Further, in some embodiments, the inner diameter of the water drain hole 414 is not smaller than 2.5mm, so that the situation that the water drain hole 414 is sealed by liquid is further reduced, and water in the mounting groove 41 can smoothly flow out through each water drain hole 414.

In a preferred embodiment, the drain hole 414 is rectangular. It is understood that the shape of the downcomer aperture 414 is not limited thereto, and in other embodiments, the downcomer aperture 414 may be regular or irregular in shape, such as square, pentagon, hexagon, etc. It will be appreciated that the shapes and sizes of the drain holes 414 may be the same or different, and the drain holes 414 at different positions may be set to different shapes and sizes according to the positions of the drain holes 414 and the drain speed, so as to meet different requirements and achieve a better infiltration effect.

In some embodiments, all of the drainage holes 414 are spaced apart along the second direction, and the pitch d between two adjacent drainage holes 414 is 4mm to 11mm. Specifically, if the pitch of the two adjacent water drainage holes 414 is too large, it may cause that some positions of the wet curtain 60 corresponding to the space between the two water drainage holes 414 cannot be wetted, while if the pitch of the two adjacent water drainage holes 414 is too small, it may cause that the water flow flowing into the wet curtain 60 is too large and too much, resulting in waste of power supply and water flow of the water pump, and further causing negative effects such as increased cost and waste of resources. Therefore, the hole distance d between two adjacent water drain holes 414 is set to be 4mm-11mm, so that the uniform wetting of the wet curtain 60 can be ensured, the waste of resources can be effectively reduced, and the use cost of the humidifier is reduced.

It will be appreciated that the arrangement of the water drain holes 414 is not limited, and may be adjusted according to the shape of the mounting groove 41, the arrangement of other components, and the like, so as to meet the requirements of the liquid under different conditions. Specifically, in an embodiment, three sets of water draining holes 414 are formed on the liquid distributing unit 40, the three sets of water draining holes 414 are sequentially arranged along the second direction, and one set of water draining holes 414 located in the middle are arranged with the other two sets of water draining holes 414 in a dislocation manner in the third direction so as to avoid other structures.

The applicant found during the course of the study that when the wet curtain 60 is inserted from the insertion port into the installation cavity in the second direction, since the height of the installation cavity in the first direction is almost the same as the height of the wet curtain 60 in the first direction, the wet curtain 60 is easily interfered by the liquid distribution unit 40 and cannot be smoothly inserted into the installation cavity.

Based on the above-mentioned problems, the liquid distribution unit 40 of the present application is provided with the guide rib 416 protruding toward one side surface of the wet curtain 60, one end of the guide rib 416 is connected to the edge of the drain hole 414 closest to the insertion port, and the other end of the guide rib 416 extends toward the insertion port along the second direction. In this way, the liquid distribution unit 40 plays a guiding role on the wet curtain 60 by the guide rib 416 extending in the second direction contacting the wet curtain 60, so that the wet curtain 60 can be smoothly assembled into the receiving chamber.

In some embodiments, a side surface of the liquid distribution unit 40 facing the wet curtain 60 is convexly provided with a guide edge surrounding each of the drain holes 414, respectively, and water flowing out of the drain holes 414 enters the wet curtain 60 under the guidance of the guide edge. But on the other hand, when the wet curtain 60 is inserted from the insertion opening into the installation cavity in the second direction, the wet curtain 60 may be caught in the gap between the adjacent two leading edges due to the presence of the protruding leading edges.

Therefore, the liquid distribution unit 40 of the present application is provided with the limiting ribs 418 protruding toward one side surface of the wet curtain 60, each limiting rib 418 is connected between the guiding edges of two adjacent water draining holes 414, and each limiting rib 418 extends along the second direction, so that the wet curtain 60 can be prevented from being interfered by the protruding guiding edges during the insertion process of the wet curtain 60 into the installation cavity, and the wet curtain 60 can be more smoothly inserted into the installation cavity.

As a preferred embodiment, the height of the guiding edge protruding from the surface of the liquid distribution unit 40 is slightly higher than the height of the guiding rib 416 and the limiting rib 418 protruding from the surface of the liquid distribution unit 40, so that the guiding function of the guiding edge is not affected while the guiding and interference preventing functions are achieved. In other embodiments, the guide edge may also be flush with the guide rib 416 and the stop rib 418.

Referring to fig. 3, 4 and 5, fig. 3 is a side view of a wet curtain according to an embodiment of the present application, fig. 4 is a top view of a wet curtain according to an embodiment of the present application, and fig. 5 is a front view of a wet curtain according to an embodiment of the present application.

In some embodiments, the wet curtain 60 includes a wet curtain body 61, the wet curtain body 61 is in a cuboid-shaped stacked structure formed by folding fiber paper, the wet curtain body 61 obtained by folding fiber paper includes a plurality of lamination sheets, all lamination sheets are connected end to end along the second direction, folds extending along the first direction are formed between adjacent lamination sheets, and a distance (i.e. a folding distance) L between two adjacent lamination sheets is 3mm-5mm.

When the overall lengths of the wet curtain body 61 in the first direction are the same, the maximum distance between two adjacent lamination sheets is too large or too small, which affects the humidification amount of the humidifier, and the distance L between two adjacent lamination sheets of the present application is 3mm-5mm, so that the humidification amount of the humidifier is in an optimal range.

In some embodiments, compared with the wet curtain body 61 formed by non-woven fabrics and other materials, the wet curtain body 61 is formed by fiber paper, and compared with the non-woven fabrics and other materials, the fiber paper has the characteristics of lighter weight, lower price and faster drying speed, and is not easy to grow bacteria after long-time use, so that the problem of mildew and odor of the wet curtain body 61 is relieved to a certain extent, and the service life of the wet curtain 60 is prolonged.

In some embodiments, each lamination is provided with a plurality of spaced apart water punctures 612, each water puncture 612 having a circular-like aperture with a diameter of 1.5mm-2mm, and the air flow generated by the air duct assembly may pass through the wet curtain 60 via the water punctures 612. On the contrary, if the diameter of the water puncture 612 is too small, the liquid seal phenomenon is easy to generate to block the airflow from flowing through, if the diameter of the water puncture 612 is too large, the effective evaporation area of the wet curtain body 61 is too small, the evaporation effect of the moisture is affected, and the humidification effect of the humidifier is further affected.

In some embodiments, the wet curtain 60 further includes at least two fixing ribs 63 formed on the wet curtain body 61, all of the fixing ribs 63 being spaced apart in the first direction, each of the fixing ribs 63 extending from one side to the other side of the wet curtain body 61 in the second direction, thereby functioning as a fixing space, supporting the shape of the wet curtain body 61. In particular, in some embodiments, the securing ribs 63 are formed by applying glue to the surface of the wet curtain body 61.

As a preferred embodiment, the distance H between two adjacent fixing ribs 63 is 25.4mm or 50.8mm, preferably 25.4mm. In the conventional art, since the fixing ribs 63 are formed on the surface of the wet curtain body 61, the amount of moisture on the wet curtain body 61 is hindered, and therefore, the smaller the number of the fixing ribs 63 on the wet curtain 60, the larger the water absorption area and the air passing area of the wet curtain 60, and the amount of moisture added to the wet curtain 60 can be increased. However, the applicant has found during the course of the study that a suitable increase in the number of fixing ribs 63 makes the fixing of the wet curtain body 61 more firm, the folding distance between the laminations more uniform, which in turn increases the overall humidification of the wet curtain 60. Thus, the interval H between the adjacent two fixing ribs 63 is 25.4mm or 50.8mm, unlike the interval between the adjacent two fixing ribs 63 of the prior art, which is 101.6mm.

In some embodiments, the wet curtain 60 further includes an upper water end piece and a lower water end piece (not shown), which are fixedly connected to the upper and lower ends of the wet curtain body 61 in the first direction, respectively, and are made of a water absorbing material (e.g., needle punched cotton) having excellent water absorbing ability.

In this way, the water flowing out of the drain hole 414 can be absorbed by the upper water end piece, then transferred to the wet curtain body 61, and after the wet curtain body 61 is fully wetted, the water reaching the lower water end piece is absorbed and discharged by the lower water end piece. Under the buffering of the water feeding end piece, the water of the cloth liquid can be transferred to the whole wet curtain body 61 more stably and uniformly, and the phenomenon that water flow is concentrated and unstable to cause excessive water accumulation in a large living time can be effectively avoided. Further, after wetting the wet curtain body 61, the surplus moisture is absorbed and discharged by the entire drain terminal, so that the accumulation of moisture can be prevented, and thus, the flying water can be prevented.

In other embodiments, based on the wet curtain body 61 formed by the fiber paper having good wetting performance, the wet curtain 60 may not be provided with an upper water end piece and a lower water end piece, the wet curtain body 61 is directly contacted with the liquid distribution unit 40, and the water flowing out of the lower water hole 414 may directly enter the wet curtain body 61, thereby simplifying the construction of the wet curtain 60, further reducing the production cost of the wet curtain 60, and being not easy to mold and smell.

Above-mentioned wet curtain subassembly 100 and be equipped with its humidifier, the water in the cloth liquid unit 40 can flow into wet curtain 60 through special design's apopore 414, and cooperation wet curtain body 61's water thorn hole 612's aperture, roll over the pitch and the interval design of fixed rib 63, wet curtain 60 can fully wet, has effectively promoted the humidification volume. Furthermore, the arrangement of the guide ribs 416 and the limit ribs 418 improves the smoothness of the installation of the wet curtain 60. In addition, the wet curtain body 61 formed by the fiber paper effectively relieves the problem of mildew and odor of the wet curtain body 61 due to long-term wet state while remarkably reducing the cost, and finally improves the use experience of the humidifier.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the application, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application. Accordingly, the scope of protection of the present application is to be determined by the appended claims.
