[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description herein is for describing the specific embodiments only and is not intended to be limiting of the present application. Specific Implementation

[0036] like Figures 1-3 As shown, this embodiment provides a wet curtain assembly 10, including a wet curtain 11 and a wet curtain bracket 12 for fixing the wet curtain 11. In the vertical direction, a water inlet trough 121 is horizontally arranged at the top of the wet curtain bracket 12 and a water inlet pipe 122 is horizontally arranged in the middle. Humidification holes 126 are respectively provided on the water inlet trough 121 and the water inlet pipe 122 to supply water to the wet curtain 11.

[0037] In existing technical solutions, water is usually added to the wet curtain 11 from the top. Because the wet curtain 11 is absorbent and breathable, the water at the top of the wet curtain 11 gradually seeps downwards under the action of gravity to wet the entire wet curtain 11. Then, the fan 30 works to introduce dry air from outside into the air humidifier 100. After passing through the wet wet curtain 11, the air carries water vapor and is finally blown outside the air humidifier 100 to humidify the indoor air. However, when the water supply to the top of the wet curtain 11 is insufficient, or when the surface area of ​​the wet curtain 11 is large, the bottom of the wet curtain 11 may not be fully wetted. In this case, the dry air does not pass through the unwetted wet curtain 11 and cannot carry water vapor to humidify the indoor air, resulting in an unsatisfactory humidification effect.

[0038] In this embodiment, the evaporative cooling pad 11 is fixed inside the evaporative cooling pad bracket 12. The size of the evaporative cooling pad bracket 12 is slightly larger than the size of the evaporative cooling pad 11. A water inlet trough 121 is horizontally arranged at the top of the evaporative cooling pad bracket 121. A humidification hole 126 is arranged on the bottom wall of the water inlet trough 121. The humidification hole 126 faces the top of the evaporative cooling pad 11 in the vertical direction. Water in the water inlet trough 121 is added to the top of the evaporative cooling pad 11 along the humidification hole 126. The water at the top of the evaporative cooling pad 11 gradually seeps downward under the action of gravity. At the same time, a water inlet pipe 122 is horizontally arranged in the middle of the evaporative cooling pad bracket 122. A humidification hole 126 is arranged on the side of the water inlet pipe 122 facing the surface of the evaporative cooling pad 11. Water in the water inlet pipe 122 is added to the middle of the evaporative cooling pad 11 along the humidification hole 126. The water in the middle of the evaporative cooling pad 11 gradually seeps downward under the action of gravity.

[0039] The beneficial effect of this embodiment is that by setting a water inlet pipe 122 in the middle of the wet curtain bracket 12, and cooperating with the water inlet trough 121 at the top, water can be added to the wet curtain 11 from the top and middle at the same time. Compared with the existing scheme of adding water only from the top of the wet curtain 11, the wet curtain 11 can be fully wetted.

[0040] Combination Figure 1In a more preferred embodiment, the bottom of the wet curtain support 12 is provided with a water supply port 123 for supplying water to the water supply tank 121, and a water supply channel 13 is arranged between the water supply port 123 and the water supply tank 121. Specifically, the water supply port 123 is arranged at one side of the bottom of the wet curtain support 12, and the water supply channel 13 is arranged at the side wall of the wet curtain support 12 at the same side as the water supply port 123, and the water supply channel 13 cooperates with the water pump to realize water supply from bottom to top. The water supply channel 13 can be a pipeline connected between the water supply port 123 and the water supply tank 121, which is arranged in the frame structure of the side wall of the wet curtain support 12, or the water supply channel 13 can be a water flow channel integrally formed with the side wall of the wet curtain support 12. The water supply channel 13 in this embodiment has a compact structure, can save the internal space of the air humidifier 100, and is easy to assemble and maintain.

[0041] In combination Figures 4-5 In a more preferred embodiment, the bottom wall of the water supply tank 121 is provided with an overflow port 1211, a partition 1212 is arranged in the water supply tank 121 to separate the overflow port 1211, and an overflow channel 14 is arranged between the overflow port 1211 and the water supply pipe 122. The excess water in the water supply tank 121 overflows the partition 1212 to the overflow port 1211 and flows into the water supply pipe 122 along the overflow channel 14. Specifically, the overflow port 1211 is arranged at one side of the bottom wall of the water supply tank 121, and the overflow channel 14 is arranged at the side wall of the wet curtain support 12 at the same side as the overflow port 1211. Further, the overflow channel 14 is a pipeline connected between the overflow port 1211 and the water supply pipe 122, and the connection between the overflow channel 14 and the water supply pipe 122 is in an L shape. Further, the overflow channel 14 and the water supply channel 13 are arranged at the same side of the wet curtain support 12. In this embodiment, the water in the water supply tank 121 supplies water to the water supply pipe 122 in an overflow manner, which on one hand, first ensures that there is sufficient water in the water supply tank 121 to supply water from the top of the wet curtain 11, avoiding the problem of insufficient water supply to the upper part of the wet curtain 11; on the other hand, no additional power device is needed to supply water to the water supply pipe 122, saving cost.

[0042] In a more preferred embodiment, the water supply pipe 122 and the water supply channel 13 are communicated, and part of the water entering the water supply channel 13 from the water supply port 123 flows into the water supply tank 121, and the other part flows into the water supply pipe 122. In this embodiment, the water supply channel 13 directly supplies water to the water supply tank 121 and the water supply pipe 122 at the same time, and the connection between the water supply channel 13 and the water supply pipe 122 is in a T shape. Compared with the above-mentioned embodiment, the overflow channel 14 is omitted, and the structure is simpler.

[0043] In a more preferable embodiment, the number of water supply pipes 122 is multiple, and the multiple water supply pipes 122 are spaced apart in the vertical direction of the wet curtain support 12, and each water supply pipe 122 is in communication with the water supply channel 13. Specifically, the more the number of water supply pipes 122 is distributed in the vertical direction of the wet curtain support 12, the better the wetting effect on the wet curtain 11, but the structure is more complex and the cost is higher; therefore, considering the size of the commonly used wet curtain 11 on the market, usually one or two water supply pipes 122 can meet the actual application requirements, and the wet curtain 11 is fully wetted, and the humidification effect is good.

[0044] In combination Figure 2 In a more preferable embodiment, the wet curtain 11 is in a double-layer distribution structure, the water supply pipe 122 is located inside the wet curtain 11, and the humidification holes 126 on the water supply pipe 122 are respectively directed to the wet curtains 11 on both sides. Specifically, the support rod 127 is transversely arranged above the frame space of the wet curtain support 12, the extension direction of the support rod 127 is consistent with the extension direction of the water supply groove 121 and the water supply pipe 122, the water supply groove 121 is located directly above the support rod 127, and the water supply pipe 122 is located directly below the support rod 127. The top of the wet curtain 11 is folded to form a double-layer structure over the support rod 127, and the water supply pipe 122 is located inside the double-layer wet curtain 11. The water in the water supply groove 121 flows to the top of the wet curtain 11 through the humidification holes 126, and penetrates downward along the wet curtains 11 on both sides; at the same time, the water in the water supply pipe 122 flows to the wet curtains 11 on both sides through the humidification holes 126 on both sides of the water supply pipe 122, and penetrates downward along the middle part of the wet curtains 11 on both sides.

[0045] In combination Figure 3 In a more preferable embodiment, the humidification holes 126 are spaced apart on the bottom wall of the water supply groove 121, and the humidification holes 126 extend a distance towards the wet curtain 11. In this embodiment, the humidification holes 126 on the bottom wall of the water supply groove 121 extend a distance towards the wet curtain 11, so that the water in the water supply groove 121 directly falls on the wet curtain 11 under the action of gravity, reducing the situation of overflowing to the outside.

[0046] In a more preferable embodiment, the humidification holes 126 are special-shaped holes. Specifically, the humidification holes 126 are non-smooth holes such as squares or polygons, which can avoid the problem that a water film is formed at the humidification holes 126, causing poor water flow and failing to timely wet the wet curtain 11.

[0047] In combination Figure 1In a more preferable embodiment, the bottom of the wet curtain support 12 is provided with a water collecting groove 124, and the bottom wall of the water collecting groove 124 is provided with a water outlet 1241, through which the water in the water collecting groove 124 flows out of the wet curtain support 12. In this embodiment, the water that penetrates downward from the top and middle of the wet curtain 11 is collected in the water collecting groove 124 and flows out through the water outlet 1241 to the water tank 40 below the wet curtain support 12. The water in the water tank 40 is pumped to the wet curtain 11 to realize water recycling.

[0048] In a more preferable embodiment, the wet curtain assembly 10 is in the shape of a flat plate or a hollow cylinder. Specifically, when the wet curtain assembly 10 is in the shape of a flat plate, the wet curtain 11 is also in the shape of a flat plate, and the airflow carries water vapor by penetrating the wet curtain 11 in a direction perpendicular to the surface of the wet curtain 11; when the wet curtain assembly 10 is in the shape of a hollow cylinder, the wet curtain 11 is also in the shape of a hollow cylinder, and the airflow carries water vapor by penetrating the wet curtain 11 from the circumferential side of the wet curtain 11 inward.

[0049] In combination Figures 4-5 In a more preferable embodiment, the wet curtain support 12 is provided with fixed plates 125 that are transversely and longitudinally staggered on the air inlet side and the air outlet side of the wet curtain 11, and the transversely distributed fixed plates 125 are inclined at an acute angle to the horizontal direction. Specifically, when the air penetrates the wet curtain 11, the wet curtain 11 is prone to shrink due to deformation caused by the air, which in turn affects the humidification effect because the wet curtain 11 cannot be fully wetted. The fixed plates 125 are used to fix the wet curtain 11 to prevent deformation, and the fixed plates 125 are staggered to form a plurality of air passages for the air to penetrate. The transversely distributed fixed plates 125 are inclined at an acute angle to the horizontal direction, that is, the end of the transversely distributed fixed plates 125 away from the surface of the wet curtain 11 is inclined upward. In this way, when the excess water on the wet curtain 11 flows onto the transversely distributed fixed plates 125, the water converges toward the end of the surface of the wet curtain 11 and can be absorbed by the wet curtain 11 or continue to flow downward along the surface of the wet curtain 11, thereby avoiding water overflow.

[0050] In combination Figure 5 In a more preferable embodiment, the fixed plates 125 are each provided with a surrounding plate 1251 at the end away from the wet curtain 11. Specifically, the fixed plates 125 are each in abutment with the surface of the wet curtain 11 at one end and are each provided with a surrounding plate 1251 at the other end, and the surrounding plate 1251 is perpendicular to the overflow direction of the water to block the water overflow. When the excess water on the wet curtain 11 flows downward along the surface of the wet curtain 11, part of the water flows downward along the longitudinally distributed fixed plates 125, and the surrounding plate 1251 on the longitudinally distributed fixed plates 125 blocks the water overflow, and the other part of the water flows onto the transversely distributed fixed plates 125, and the surrounding plate 1251 on the transversely distributed fixed plates 125 blocks the water overflow. In this way, the excess water on the wet curtain 11 can only flow downward along the surface of the wet curtain 11 and finally converges into the water collecting groove 124 at the bottom of the wet curtain support 12, thereby avoiding water flowing to other components.

[0051] Further, the horizontal distance between the transversely distributed edge plate 1251 and the wet curtain 11 is greater than the horizontal distance between the longitudinally distributed edge plate 1251 and the wet curtain 11. In this way, when the excess water on the wet curtain 11 flows down along the longitudinally distributed fixed plate 125 to the transversely distributed fixed plate 125, the water is blocked by the transversely distributed edge plate 1251 and does not overflow along the longitudinally distributed edge plate 1251 to the outside of the wet curtain 11.

[0052] In combination Figure 6 The air humidifier 100 starts, the water pump in the water tank 40 starts to work, water in the water tank 40 is pumped to the wet curtain assembly 10; at the same time, the fan 30 operates, the dry air outside is sucked into the air humidifier 100, the dry air carries water vapor after passing through the wet curtain assembly 10, and then is discharged from the air humidifier 100, so that the purpose of humidifying indoor air is achieved.

[0053] The above is only a specific implementation of the present application, so that those skilled in the art can understand or implement the present disclosure. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
