The wet curtain assembly further includes a wet curtain assembly water distribution cover, a wet curtain and a wet curtain lower cover, and an upper water pipe for supplying water to the wet curtain assembly. The lower end of the upper water pipe is sealingly connected to the water inlet hole on the wet curtain lower cover, and the water inlet hole on the wet curtain lower cover is sealingly connected to the water inlet hole on the wet curtain support. In order to ensure the sealing connection between the wet curtain support, the wet curtain lower cover and the upper water pipe, a silica gel ring is installed on the wet curtain lower cover to realize the sealing connection of the wet curtain support through the silica gel ring. During installation, the wet curtain assembly can be assembled into a whole, and then the wet curtain assembly is installed on the wet curtain support. Due to the softness and easy deformation of the silica gel part, when the wet curtain assembly is installed on the wet curtain support, the silica gel part may be deformed or even displaced due to improper installation or excessive force, which cannot ensure the good cooperation between the upper water pipe and the water inlet hole of the wet curtain support, resulting in a decrease in the amount of water supply and an undesirable humidification amount.

[0003] Therefore, how to ensure the good cooperation between the upper water pipe and the water inlet hole of the wet curtain support has become a problem to be solved. CONTENT OF THE UTILITY MODEL

[0004] The utility model aims at least solves the technical problem that the wet curtain device in prior art or related art cannot ensure the good cooperation between the upper water pipe and the water inlet hole of the wet curtain support after assembly.

[0005] Therefore, the utility model aims at providing a wet curtain device.

[0006] The embodiment of the second aspect of the present application provides an air conditioning device.

[0007] The utility model discloses a technical scheme of first aspect provides a kind of wet curtain device, for air conditioning device, wet curtain device includes: wet curtain support, water guide column is provided on wet curtain support, water guide column is provided with water inlet passage;Wet curtain assembly, detachably installed on wet curtain support, wet curtain assembly includes wet curtain lower cover and water pipe, wet curtain lower cover or wet curtain support is provided with mounting hole;Sealing ring, installed in mounting hole, mounting groove is provided on the inner wall of mounting hole, and mounting groove includes the first groove wall surface and the second groove wall surface being oppositely spaced along the axial direction of mounting hole, first positioning portion is provided on the outer wall of sealing ring, first positioning portion is installed in mounting groove, and the two faces of first positioning portion along the axial direction of sealing ring are respectively with the first groove wall surface and the second groove wall surface abut;Wherein, when wet curtain assembly is installed on wet curtain support, the first end of water pipe is installed in sealing ring, one end of water guide column is installed in sealing ring, and water inlet passage is communicated with water pipe.

[0008] According to the wet curtain device provided by the embodiment of the utility model, the wet curtain device is used for air conditioning device to humidify air. The wet curtain device includes a wet curtain support and a wet curtain assembly installed on the wet curtain support. The wet curtain assembly is detachably installed on the wet curtain support through a wet curtain lower cover. The wet curtain assembly is supported by the wet curtain support to avoid being soaked in water for a long time. The wet curtain assembly specifically includes the wet curtain lower cover and a water pipe. External water enters the mounting hole through the water inlet passage on the wet curtain support, and then enters the water pipe from the mounting hole. The water is then delivered to the wet curtain assembly by the water pipe. In addition, a sealing ring is installed in the mounting hole to ensure the sealed connection between the water pipe, the water guide column and the wet curtain lower cover. When the wet curtain assembly is installed on the wet curtain support, part of the sealing ring is sleeved outside the water pipe to ensure the sealed connection between the wet curtain lower cover and the water pipe. Another part of the sealing ring is sleeved outside the water guide column to ensure the sealed connection between the wet curtain lower cover and the wet curtain support.

[0009] The installation hole is further provided with an installation slot. The first positioning part on the outer side wall of the sealing ring can be limitedly installed in the installation slot. When installing the wet curtain device, the wet curtain lower cover, the upper water pipe and the like can be assembled into an integral whole, then the sealing ring is installed, and finally the wet curtain assembly is installed on the wet curtain support from top to bottom. In the installation of the wet curtain device, if the wet curtain support and the wet curtain assembly are not accurately aligned, the water guide column or the upper water pipe will extrude the sealing ring, causing the sealing ring to deform. At this time, since the upper and lower sides of the first positioning part of the sealing ring are pressed and fixed by the first slot wall surface and the second slot wall surface of the installation slot, when the sealing ring has a deformation trend, the first positioning part will inhibit the deformation of the sealing ring, ensuring that the deformation of the sealing ring is relatively small. This allows the water guide column or the water guide pipe to be smoothly inserted into the sealing ring and allows the water guide column and the upper water pipe to be sealedly connected. It can be seen that the limitation of the first slot wall surface and the second slot wall surface on the first positioning part can better fix the sealing ring, so that the sealing ring is less likely to deform in the installation hole. This can ensure the good cooperation between the water guide column and the upper water pipe, thereby better ensuring the water supply amount of the wet curtain assembly to ensure the humidification amount of the air conditioning device.

[0010] In any of the above embodiments, optionally, the wet curtain assembly further comprises: a wet curtain installed on the side of the wet curtain lower cover away from the wet curtain support; and a water distribution cover installed on the side of the wet curtain away from the wet curtain lower cover, the second end of the upper water pipe being in communication with the water distribution cover.

[0011] In this embodiment, the wet curtain assembly further comprises a wet curtain, which is a core component of the wet curtain assembly and can be a hydroentangled fabric that can be fully wetted to humidify air. The water in the upper water pipe can be delivered to the wet curtain to fully wet the wet curtain assembly and thereby humidify air.

[0012] Further, the top of the wet curtain assembly is further provided with a water distribution cover for uniformly distributing the water delivered by the upper water pipe to the wet curtain to fully wet the wet curtain. With this arrangement, the water on the wet curtain assembly can reach the wet curtain from the top of the wet curtain assembly, allowing the water on the wet curtain assembly to be more evenly distributed, so that air can be evenly humidified.

[0013] Of course, in other solutions, the wet curtain assembly can also adopt other structures, such as not providing a water distribution cover and directly spraying the water in the upper water pipe to the wet curtain.

[0014] In any of the above embodiments, optionally, the sealing ring is in interference fit with the upper water pipe, and the sealing ring is in interference fit with the water guide column.

[0015] In this embodiment, the sealing connection between the upper water pipe and the water guide column can be better through the interference fit between the sealing ring and the upper water pipe and the interference fit between the sealing ring and the water guide column, so that the water leakage can be avoided when the water is supplied to the wet curtain assembly.

[0016] In any of the above embodiments, optionally, a first protruding rib and a second protruding rib are arranged on the inner side wall of the mounting hole, and the first protruding rib, the second protruding rib and the inner side wall of the mounting hole enclose a mounting groove.

[0017] In this embodiment, two protruding ribs can be arranged on the inner side wall of the mounting hole to form a mounting groove through the two protruding ribs, so as to limit and fix the first positioning part of the sealing ring, so that the sealing ring can be fixed by the two protruding ribs to avoid deformation of the sealing ring during assembly of the wet curtain device.

[0018] Of course, in other solutions, a circle of material can also be removed inwardly from the inner side wall of the mounting hole to form a mounting groove to accommodate the first positioning part, that is, the first protruding rib and the second protruding rib herein can also be formed by removing a circle of material inwardly from the inner side wall of the mounting hole.

[0019] The axial height of the first protruding rib can extend to the end face of the mounting hole in a direction away from the second protruding rib. The second protruding rib can extend to the other end face of the mounting hole in a direction away from the first protruding rib, that is, the upper side wall of the mounting groove is formed as a whole by the first protruding rib, and the lower side wall of the mounting groove is formed as a whole by the second protruding rib, except for the part of the mounting groove.

[0020] In any of the above embodiments, optionally, the first positioning part includes a third protruding rib arranged on the outer side wall of the sealing ring.

[0021] In this embodiment, a third protruding rib can be arranged on the outer side wall of the sealing ring, and the third protruding rib is used for the first positioning part, so as to realize the positioning between the sealing ring and the wet curtain support. Of course, other structures can also be arranged on the outer side wall of the sealing ring to form the first positioning part.

[0022] In any of the above embodiments, optionally, the mounting hole is arranged on the lower cover of the wet curtain, and when the wet curtain assembly is mounted on the wet curtain support, part of the sealing ring is limited between the inner wall of the mounting hole and the outer wall of the upper water pipe, and part of the sealing ring is limited between the inner wall of the mounting hole and the outer wall of the water guide column.

[0023] In this embodiment, the sealing ring is installed in the mounting hole of the lower cover of the wet curtain. When the wet curtain assembly is assembled on the wet curtain support, one end of the water pipe is inserted into the sealing ring, and one end of the water guide column is inserted into the other end of the sealing ring, so that part of the sealing ring is limited between the mounting hole and the water pipe, and the other part is limited between the mounting hole and the water guide column. Therefore, when the wet curtain assembly is assembled on the wet curtain support, the water guide column and the water pipe can be connected in the lower cover of the wet curtain, and the connection between them is sealed.

[0024] In this structure, when the wet curtain device is installed, if the mounting hole and the water guide column are not accurately aligned, the water guide column of the wet curtain support will press the bottom of the sealing ring, causing the sealing ring to deform. At this time, since the upper and lower sides of the first positioning part of the sealing ring are tightly fixed by the two groove walls of the mounting groove, when the sealing ring has a tendency to deform, the first positioning part will inhibit the deformation of the sealing ring, ensuring that the deformation of the sealing ring is relatively small. This allows the water guide column to be smoothly inserted into the sealing ring and installed in the mounting hole. As can be seen, through the limitation of the two groove walls of the mounting groove, the sealing ring can be better fixed, making it less likely to deform in the mounting hole. This allows the water guide column to be better inserted and installed in the mounting hole, ensuring good cooperation between the water guide column and the water pipe. This can better ensure the water supply of the wet curtain assembly, thereby ensuring the humidification amount of the air conditioning device.

[0025] Of course, the mounting hole can also be provided on the wet curtain support, and one end of the water pipe is directly installed in the wet curtain support. In this structure, when the wet curtain assembly is installed, the sealing ring can be fixed on the wet curtain support to prevent the sealing ring from deforming under the action of the water pipe.

[0026] In any of the above embodiments, optionally, a fourth protruding rib is provided on the inner side wall of the sealing ring. When the wet curtain assembly is installed on the wet curtain support, the water pipe and the fourth protruding rib abut on one side along the axial direction of the mounting hole, and the water guide column and the fourth protruding rib abut on the other side along the axial direction of the mounting hole.

[0027] In this embodiment, a fourth protruding rib can be provided on the inner side of the sealing ring. The fourth protruding rib can enhance the strength of the sealing ring, making it less likely to deform. On the other hand, the upper part of the fourth protruding rib contacts the water pipe, and the lower part contacts the top of the water guide column of the wet curtain support. In this structure, the water pipe and the water guide column press the sealing ring at the fourth protruding rib, ensuring good conduction of the mounting hole. In addition, by providing the fourth protruding rib, the installation position of the water pipe and the water guide column in the height direction of the wet curtain assembly can be limited.

[0028] In any of the above embodiments, optionally, the mounting groove is located on the side of the fourth protruding rib close to the wet curtain support along the axial direction of the mounting hole.

[0029] In this embodiment, the installation groove is arranged relatively low, and the second protruding rib is arranged relatively high, that is, the lower end of the sealing ring is fixedly installed on the lower cover of the wet curtain through the first positioning part. This structure makes the lower end of the sealing ring have a certain length, so that the length of the contact between the sealing ring and the water guide column can be ensured, thereby improving the connection stability between the wet curtain support and the lower cover of the wet curtain.

[0030] In any of the above embodiments, optionally, a first protruding rib and a second protruding rib are arranged on the inner side wall of the installation hole, and the first protruding rib, the second protruding rib and the inner side wall of the installation hole surround the installation groove. The second protruding rib is located on the side of the first protruding rib away from the wet curtain support along the axial direction of the installation hole, and the end of the second protruding rib away from the first protruding rib along the axial direction of the installation hole is flush with the fourth protruding rib or is located on the side of the fourth protruding rib away from the wet curtain support; the end of the sealing ring away from the wet curtain support is protruded from the end of the second protruding rib away from the first protruding rib along the axial direction of the installation hole. In other words, from the direction of the wet curtain support to the lower cover of the wet curtain, the second protruding rib is higher than or flush with the fourth protruding rib, but lower than the top of the sealing ring.

[0031] In this embodiment, the second protruding rib is located on the side of the first protruding rib away from the wet curtain support along the axial direction of the installation hole, that is, the second protruding rib is located on the upper side, and the first protruding rib is located on the lower side. The second protruding rib is located on the side of the first protruding rib away from the wet curtain support along the axial direction of the installation hole, that is, the upper end of the second protruding rib extends to a position higher than or flush with the fourth protruding rib along the axial direction of the installation hole. This arrangement makes the second protruding rib have a certain height, so that the upper end of the sealing ring can be supported by the second protruding rib to avoid deformation of the upper end of the sealing ring, thereby solving the problem that the upper end of the sealing ring is prone to deformation and the position of the upper water pipe is prone to deviation. At the same time, the upper end of the sealing ring is higher than the second protruding rib, that is, the second protruding rib is lower than the highest end of the sealing ring, so that the sealing ring can better cooperate with the upper water pipe.

[0032] In any of the above embodiments, optionally, a flange extending in the radial direction of the sealing ring is arranged on the end of the end of the sealing ring close to the wet curtain support, a recess is arranged on the side of the lower cover of the wet curtain close to the wet curtain support, the installation hole penetrates the bottom of the recess, and the flange is limited in the recess.

[0033] In this embodiment, a flange can be arranged at the lower end surface of the sealing ring, and then the flange can be limited and installed in the recess. This arrangement can limit the axial installation position of the sealing ring through the flange. At the same time, by arranging the recess, the lower end of the sealing ring can be built-in in the lower cover of the wet curtain, thereby realizing hidden installation of the sealing ring and avoiding the situation that the sealing ring protrudes from the bottom of the lower cover of the wet curtain.

[0034] In any of the above embodiments, optionally, a guide chamfer is arranged on the end of the sealing ring close to the one end of the wet curtain support, and the guide chamfer can guide the water guide column to be inserted into the sealing ring.

[0035] In this embodiment, the guide chamfer can guide the water guide column to be inserted into the sealing ring more smoothly, so as to ensure the good cooperation between the water guide column and the upper water pipe.

[0036] In any of the above embodiments, optionally, the lower end of the sealing ring is flush with the surface of the wet curtain lower cover close to the wet curtain support in the axial direction of the mounting hole.

[0037] In this embodiment, the lower end of the sealing ring is arranged in the wet curtain lower cover, so that the sealing ring is installed in a hidden manner, and the sealing ring is prevented from protruding from the bottom of the wet curtain lower cover. For example, a groove is arranged at the bottom of the wet curtain lower cover, and the bottom of the sealing ring is arranged in the groove, so that the lower end of the sealing ring is prevented from protruding from the wet curtain lower cover.

[0038] In any of the above embodiments, optionally, the wet curtain lower cover comprises a lower cover body, a mounting protrusion arranged on the lower cover body and protruding away from the wet curtain support relative to the lower cover body, and the mounting hole penetrates through the mounting protrusion and the lower cover body.

[0039] In this embodiment, the wet curtain lower cover comprises the lower cover body and the mounting protrusion. The mounting protrusion can ensure that the mounting hole has a high length, so that the cooperation length between the mounting hole and the water guide column and the cooperation length between the mounting hole and the upper water pipe can be ensured, and the wet curtain lower cover, the water guide column and the upper water pipe are prevented from being separated from each other. In addition, the lower cover body can be designed to be thin without thickening the lower cover body, so that the cost of the wet curtain lower cover can be reduced.

[0040] In any of the above embodiments, optionally, the lower cover body and the mounting protrusion are in an integrated structure.

[0041] In this embodiment, the lower cover body and the mounting protrusion are in an integrated structure, for example, the lower cover body and the mounting protrusion are integrally injection molded, so that the connection strength between the lower cover body and the mounting protrusion can be ensured.

[0042] In any of the above embodiments, optionally, the outer side wall surface of the one end of the mounting protrusion close to the lower cover body is in a cylindrical surface, and the outer side wall surface of the one end of the mounting protrusion away from the lower cover body is in a conical surface.

[0043] In this embodiment, the lower part of the mounting protrusion is in a cylindrical structure, and the upper part of the mounting protrusion is in a conical structure, that is, the outer wall surface of the mounting protrusion remains unchanged from bottom to top and then gradually decreases.

[0044] In any of the above embodiments, optionally, the sealing ring is a silica gel ring and / or a rubber ring.

[0045] In this embodiment, the sealing ring can be specifically a silica gel ring and / or a rubber ring. The material thereof can be set as required.

DETAILED DESCRIPTION

[0058] In order to enable the above-mentioned objects, features and advantages of the present application to be more clearly understood, the following will further describe the present application with reference to the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0059] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in other ways different from those described herein, and therefore, the scope of the present application is not limited to the specific embodiments disclosed below.

[0060] The embodiments of the present application will be described below with reference to Figures 1 to 4 to describe a wet curtain device 100 and an air conditioning device provided by the embodiments of the present application.

[0061] As shown in Figures 1 to 4 , the embodiments of the first aspect of the present application provide a wet curtain device 100 for an air conditioning device. The wet curtain device 100 comprises a wet curtain support 1, a wet curtain assembly 2 and a sealing ring 29. The wet curtain support 1 is provided with a water guide column 12, and the water guide column 12 is provided with a water inlet channel 14. The wet curtain assembly 2 is detachably mounted on the wet curtain support 1. The wet curtain assembly 2 comprises a wet curtain lower cover 22 and an upper water pipe 28, and the wet curtain lower cover 22 or the wet curtain support 1 is provided with a mounting hole 222. The sealing ring 29 is mounted in the mounting hole 222, and the inner wall of the mounting hole 222 is provided with a mounting groove 225, the mounting groove 225 comprises a first groove wall surface 2252 and a second groove wall surface 2254 which are oppositely and spaced apart along the axial direction of the mounting hole 222, the outer wall of the sealing ring 29 is provided with a first positioning portion 292, the first positioning portion 292 is mounted in the mounting groove 225, and the two faces of the first positioning portion 292 along the axial direction of the sealing ring 29 are respectively in abutment with the first groove wall surface 2252 and the second groove wall surface 2254; wherein, when the wet curtain assembly 2 is mounted on the wet curtain support 1, a first end of the upper water pipe 28 is mounted in the sealing ring 29, one end of the water guide column 12 is mounted in the sealing ring 29, and the water inlet channel 14 is in communication with the upper water pipe 28.

[0062] The wet curtain device 100 according to the embodiment of the utility model provides, for air conditioning device, to humidify air. Among them, the wet curtain device 100 includes wet curtain support 1 and installs on wet curtain support 1 wet curtain assembly 2, and wet curtain assembly 2 can be detachably installed on wet curtain support 1 through wet curtain lower cover 22. Wet curtain assembly 2 can be supported by wet curtain support 1, to avoid wet curtain assembly 2 long-term soaking in water. Wet curtain assembly 2 specifically includes wet curtain lower cover 22 and upper water pipe 28, and the water outside can enter the mounting hole 222 through the water inlet channel 14 on the wet curtain support 1, then enter the upper water pipe 28 from the mounting hole 222, then be delivered to wet curtain assembly 2 by upper water pipe 28. At the same time, to ensure the sealed connection between upper water pipe 28, water guide column 12 and wet curtain lower cover 22, sealing ring 29 is also installed in mounting hole 222. When wet curtain assembly 2 is installed on wet curtain support 1, a part of sealing ring 29 is sleeved outside upper water pipe 28, to ensure the sealed connection between wet curtain lower cover 22 and upper water pipe 28, and another part of sealing ring 29 is sleeved outside water guide column 12, to ensure the sealed connection between wet curtain lower cover 22 and wet curtain support 1.

[0063] Among them, mounting hole 222 is also provided with mounting groove 225. The first positioning part 292 on the outer side wall of sealing ring 29 can be limit installed in mounting groove 225. Among them, when installing wet curtain device 100, wet curtain lower cover 22, upper water pipe 28 and the like can be assembled into a whole, then sealing ring 29 is installed, and finally wet curtain assembly 2 is installed on wet curtain support 1 from top to bottom. The structure, when installing wet curtain device 100, if wet curtain support 1 and wet curtain assembly 2 are not quite accurate in alignment, then water guide column 12 or upper water pipe 28 will extrude sealing ring 29, so that sealing ring 29 is deformed, at this time, because the upper and lower sides of the first positioning part 292 of sealing ring 29 are pressed and fixed by the first groove wall surface 2252 and the second groove wall surface 2254 of mounting groove 225, therefore, when sealing ring 29 has deformation tendency, the first positioning part 292 will inhibit the deformation of sealing ring 29, to ensure that the deformation amount of sealing ring 29 is relatively small, which makes water guide column 12 or water guide pipe can be smoothly inserted into sealing ring 29, and water guide column 12 and upper water pipe 28 are sealedly connected. It can be seen that, by limiting the first positioning part 292 through the first groove wall surface 2252 and the second groove wall surface 2254, sealing ring 29 can be fixed better, so that sealing ring 29 is less likely to be deformed in mounting hole 222, which can ensure the good cooperation between water guide column 12 and upper water pipe 28, so that the water supply amount of wet curtain assembly 2 can be better ensured, to ensure the humidification amount of air conditioning device.

[0064] In any of the above embodiments, optionally, as Figures 1 to 4As shown, the wet curtain assembly 2 further comprises a wet curtain 24 installed on the side of the wet curtain lower cover 22 away from the wet curtain support 1, and a water distribution cover 26 installed on the side of the wet curtain 24 away from the wet curtain lower cover 22, and the second end of the upper water pipe 28 is in communication with the water distribution cover 26.

[0065] In this embodiment, the wet curtain assembly 2 further comprises a wet curtain 24, which is the core component of the wet curtain assembly 2 and can be a water jet cloth, which can be fully wetted to humidify the air. The water in the upper water pipe 28 can be delivered to the wet curtain 24 to fully wet the wet curtain assembly 2 to humidify the air.

[0066] Further, as shown, Figures 1 to 4 the top of the wet curtain assembly 2 is further provided with a water distribution cover 26, which is used to evenly distribute the water from the upper water pipe 28 to the wet curtain 24 to fully wet the wet curtain 24. With this arrangement, the water on the wet curtain assembly 2 can be distributed more evenly from the top of the wet curtain assembly 2 to the wet curtain 24, so that the air can be evenly humidified.

[0067] Of course, in other solutions, the wet curtain assembly 2 can also adopt other structures, such as not setting the water distribution cover 26, but directly spraying the water in the upper water pipe 28 to the wet curtain 24.

[0068] In any of the above embodiments, optionally, the sealing ring 29 and the upper water pipe 28 are in interference fit, and the sealing ring 29 and the water guide column 12 are in interference fit.

[0069] In this embodiment, the interference fit between the sealing ring 29 and the upper water pipe 28 and the interference fit between the sealing ring 29 and the water guide column 12 can make the sealing connection between the upper water pipe 28 and the water guide column 12 better, so as to avoid the water leakage when supplying water to the wet curtain assembly 2.

[0070] In any of the above embodiments, optionally, as shown in Figure 1 , Figure 2 and Figure 3 , the inner side wall of the mounting hole 222 is provided with a first protruding rib 223 and a second protruding rib 224, and the first protruding rib 223, the second protruding rib 224 and the inner side wall of the mounting hole 222 form a mounting groove 225.

[0071] In this embodiment, two protruding ribs can be provided on the inner side wall of the mounting hole 222 to form a mounting groove 225 through the two protruding ribs to limit and fix the first positioning part 292 of the sealing ring 29, so that the sealing ring 29 can be fixed by the two protruding ribs to avoid deformation of the sealing ring 29 during assembly of the wet curtain device 100.

[0072] Of course, in other solutions, a circle of material can also be removed inwardly from the inner side wall of the mounting hole 222 to form a mounting groove 225 to accommodate the first positioning portion 292, that is, the first protruding rib 223 and the second protruding rib 224 herein can also be formed by removing a circle of material inwardly from the inner side wall of the mounting hole 222.

[0073] The axial height of the first protruding rib 223 can extend to the end face of the mounting hole 222 in a direction away from the second protruding rib 224. The second protruding rib 224 can extend to the other end face of the mounting hole 222 in a direction away from the first protruding rib 223, that is, at this time, the upper side wall of the mounting groove 225 is formed as a whole by the first protruding rib 223, and the lower side wall of the mounting groove 225 is formed as a whole by the second protruding rib 224, except for the part of the mounting groove 225.

[0074] In any of the above embodiments, optionally, as shown in Figure 4 The first positioning portion 292 includes a third protruding rib arranged on the outer side wall of the sealing ring 29.

[0075] In this embodiment, a circle of third protruding ribs can be arranged on the outer side wall of the sealing ring 29, and then the third protruding ribs are used as the first positioning portion 292, so as to realize the positioning between the sealing ring 29 and the wet curtain support 1. Of course, other structures can also be arranged on the outer side wall of the sealing ring 29 to form the first positioning portion 292.

[0076] In any of the above embodiments, optionally, as shown in Figures 1 to 3 The mounting hole 222 is arranged on the wet curtain lower cover 22, and when the wet curtain assembly 2 is mounted on the wet curtain support 1, a part of the sealing ring 29 is limited between the inner wall of the mounting hole 222 and the outer wall of the upper water pipe 28, and a part of the sealing ring 29 is limited between the inner wall of the mounting hole 222 and the outer wall of the water guide column 12.

[0077] In this embodiment, the sealing ring 29 is mounted in the mounting hole 222 of the wet curtain lower cover 22. When the wet curtain assembly 2 is assembled on the wet curtain support 1, one end of the upper water pipe 28 is inserted into the sealing ring 29, and one end of the water guide column 12 is inserted into the other end of the sealing ring 29, so that a part of the sealing ring 29 is limited between the mounting hole 222 and the upper water pipe 28, and the other part is limited between the mounting hole 222 and the water guide column 12, so that when the wet curtain assembly 2 is assembled on the wet curtain support 1, the water guide column 12 and the upper water pipe 28 can be connected to each other in the wet curtain lower cover 22, and the connection between them is sealed.

[0078] In this structure, when installing the wet curtain device 100, if the mounting hole 222 and the water guide column 12 are not aligned precisely, the water guide column 12 of the wet curtain bracket 1 will squeeze the bottom of the sealing ring 29, causing the sealing ring 29 to deform. At this time, since the upper and lower sides of the first positioning part 292 of the sealing ring 29 are pressed and fixed by the two groove walls of the mounting groove 225, when the sealing ring 29 has a tendency to deform, the first positioning part 292 will suppress the deformation of the sealing ring 29, ensuring that the deformation of the sealing ring 29 is relatively small. This allows the water guide column 12 to be smoothly inserted into the sealing ring 29 and installed into the mounting hole 222. As can be seen, the sealing ring 29 can be better fixed by the two groove walls of the mounting groove 225, making it less likely for the sealing ring 29 to deform in the mounting hole 222. This allows the water guide column 12 to be better inserted into the mounting hole 222, ensuring a good fit between the water guide column 12 and the water supply pipe 28. This better ensures the water supply of the wet curtain assembly 2, thereby ensuring the humidification of the air conditioning device.

[0079] Of course, the mounting hole 222 can also be set on the wet curtain bracket 1 (not shown in the figure of this embodiment). In this case, one end of the water supply pipe 28 is directly installed inside the wet curtain bracket 1. With this structure, when installing the wet curtain assembly 2, the sealing ring 29 can be fixed on the wet curtain bracket 1 to prevent the sealing ring 29 from deforming under the action of the water supply pipe 28.

[0080] In any of the above embodiments, optionally, as Figure 2 and Figure 4 As shown, a fourth rib 294 is provided on the inner wall of the sealing ring 29. When the wet curtain assembly 2 is installed on the wet curtain bracket 1, the water inlet pipe 28 and the fourth rib 294 abut against each other on one side of the mounting hole 222, and the water guide column 12 and the fourth rib 294 abut against each other on the other side of the mounting hole 222.

[0081] In this embodiment, a fourth rib 294 can be formed on the inner side of the sealing ring 29. The fourth rib 294 enhances the strength of the sealing ring 29, making it less prone to deformation. Furthermore, the upper part of the fourth rib 294 contacts the water inlet pipe 28, and the lower part contacts the top of the water guide column 12 of the wet curtain bracket 1. This structure allows the water inlet pipe 28 and the water guide column 12 to press against each other at the fourth rib 294, ensuring good conductivity of the mounting hole 222. In addition, the fourth rib 294 can also limit the installation position of the water inlet pipe 28 and the water guide column 12 in the height direction of the wet curtain assembly 2.

[0082] In any of the above embodiments, optionally, as Figure 1 and Figure 2 As shown, the mounting groove 225 is located on the side of the fourth rib 294 along the axial direction of the mounting hole 222, close to the wet curtain bracket 1.

[0083] In this embodiment, the installation groove 225 is arranged relatively low, and the second protruding rib 224 is arranged relatively high, that is, the lower end of the sealing ring 29 is fixedly installed on the lower cover 22 of the wet curtain through the first positioning part 292. This structure makes the lower end of the sealing ring 29 have a certain length, so that the length of the contact between the sealing ring 29 and the water guide column 12 can be ensured, thereby improving the connection stability between the wet curtain support 1 and the lower cover 22 of the wet curtain.

[0084] In any of the above embodiments, optionally, as shown in Figure 2 , the second protruding rib 224 is located on the side of the first protruding rib 223 along the axial direction of the installation hole 222 away from the wet curtain support 1, the end of the second protruding rib 224 along the axial direction of the installation hole 222 away from the first protruding rib 223 is flush with the fourth protruding rib 294, or is located on the side of the fourth protruding rib 294 away from the wet curtain support 1; the end of the sealing ring 29 away from the wet curtain support 1 is protruding from the end of the second protruding rib 224 along the axial direction of the installation hole 222 away from the first protruding rib 223. In other words, from the direction of the wet curtain support 1 to the lower cover 22 of the wet curtain, the second protruding rib 224 is higher than or flush with the fourth protruding rib 294, but lower than the top of the sealing ring 29.

[0085] In this embodiment, the second protruding rib 224 is located on the side of the first protruding rib 223 along the axial direction of the installation hole 222 away from the wet curtain support 1, that is, the second protruding rib 224 is located on the upper side, and the first protruding rib 223 is located on the lower side. The side of the second protruding rib 224 along the axial direction of the installation hole 222 away from the first protruding rib 223, that is, the upper end of the second protruding rib 224 extends along the axial direction of the installation hole 222 to a position higher than or flush with the fourth protruding rib 294. This arrangement makes the second protruding rib 224 have a certain height, so that the upper end of the sealing ring 29 can be supported by the second protruding rib 224 to avoid deformation of the upper end of the sealing ring 29, thereby solving the problem that the upper end of the sealing ring 29 is prone to deformation and the position of the upper water pipe 28 is prone to deviation. At the same time, the upper end of the sealing ring 29 is higher than the second protruding rib 224, that is, the second protruding rib 224 is lower than the highest end of the sealing ring 29, so that the sealing ring 29 can better cooperate with the upper water pipe 28.

[0086] In any of the above embodiments, optionally, as shown in Figure 2 , Figure 3 and Figure 4 , the end of the sealing ring 29 close to the wet curtain support 1 is provided with a flange 296 extending along the radial direction of the sealing ring 29, and the side of the lower cover 22 of the wet curtain close to the wet curtain support 1 is provided with a groove 226, the installation hole 222 penetrates the bottom of the groove 226, and the flange 296 is limited in the groove 226.

[0087] In this embodiment, the flange 296 can be arranged at the lower end surface of the sealing ring 29, and then the flange 296 can be limitingly installed in the groove 226. Through the flange 296, the axial installation position of the sealing ring 29 can be limited. At the same time, through the groove 226, the lower end of the sealing ring 29 can be arranged in the lower cover 22 of the wet curtain, so that the sealing ring 29 is hidden and installed, and the situation that the sealing ring 29 protrudes from the bottom of the lower cover 22 of the wet curtain is avoided.

[0088] In any of the above embodiments, optionally, as shown in Figure 2 and Figure 4 , the sealing ring 29 is provided with a guide chamfer 298 on the end of the end close to the wet curtain support 1, and the guide chamfer 298 can guide the water guide column 12 to be inserted and installed in the sealing ring 29.

[0089] In this embodiment, the guide chamfer 298 can guide the water guide column 12, so that the water guide column 12 can be more smoothly inserted and installed in the sealing ring 29, so as to ensure the good cooperation between the water guide column 12 and the upper water pipe 28.

[0090] In any of the above embodiments, optionally, as shown in Figure 2 , the sealing ring 29 is flush with the surface of the lower cover 22 close to the wet curtain support 1 along the axial direction of the installation hole 222 close to the wet curtain support 1.

[0091] In this embodiment, the lower end of the sealing ring 29 can be arranged in the lower cover 22 of the wet curtain, so that the sealing ring 29 is hidden and installed, and the situation that the sealing ring 29 protrudes from the bottom of the lower cover 22 of the wet curtain is avoided. For example, the groove 226 can be arranged at the bottom of the lower cover 22 of the wet curtain, so that the bottom of the sealing ring 29 is arranged in the groove 226, so as to ensure that the lower end of the sealing ring 29 does not protrude from the lower cover 22 of the wet curtain.

[0092] In any of the above embodiments, optionally, as shown in Figure 3 , the lower cover 22 of the wet curtain includes a lower cover body 220, an installation protrusion 221 installed on the lower cover body 220 and protruding away from the wet curtain support 1 relative to the lower cover body 220, and an installation hole 222 penetrating through the installation protrusion 221 and the lower cover body 220.

[0093] In the embodiment, the lower cover 22 of the wet curtain specifically comprises a lower cover body 220 and a mounting protrusion 221. By arranging the mounting protrusion 221, the mounting hole 222 can have a higher length, so as to ensure the fitting length between the mounting hole 222 and the water guide column 12 and between the mounting hole 222 and the upper water pipe 28, and avoid the separation of the water guide column 12, the upper water pipe 28 and the lower cover 22 of the wet curtain. In addition, the lower cover body 220 does not need to be thickened, and can be designed to be thinner, so as to reduce the cost of the lower cover 22 of the wet curtain.

[0094] In any of the above embodiments, as shown in Figure 3 the lower cover body 220 and the mounting protrusion 221 are in an integrated structure.

[0095] In the embodiment, the lower cover body 220 and the mounting protrusion 221 are in an integrated structure, for example, the lower cover body 220 and the mounting protrusion 221 can be integrally injection molded, so as to ensure the connection strength between the lower cover body 220 and the mounting protrusion 221.

[0096] In any of the above embodiments, as shown in Figure 3 the outer side wall surface of one end of the mounting protrusion 221 close to the lower cover body 220 is in a cylindrical surface 2212, and the outer side wall surface of the other end of the mounting protrusion 221 away from the lower cover body 220 is in a conical surface 2214.

[0097] In the embodiment, the lower part of the mounting protrusion 221 is in a cylindrical structure, and the upper part is in a conical structure, that is, the outer wall surface of the mounting protrusion 221 remains unchanged from bottom to top, and then gradually decreases.

[0098] In any of the above embodiments, the sealing ring 29 can be a silica gel ring and / or a rubber ring.

[0099] In the embodiment, the sealing ring 29 can specifically be a silica gel ring and / or a rubber ring. The material thereof can be arranged as required.

[0100] The second aspect of the application provides an air conditioning device, comprising the wet curtain device 100 provided in any of the first aspect embodiments. The air conditioning device comprises at least one of a humidifier, an air purifier and a water-cooled fan.

[0101] The air conditioning device provided by the embodiments of the application has all the beneficial effects of the wet curtain device 100 provided in any of the first aspect embodiments, and details are not repeated here.

[0102] In any of the above embodiments, optionally, the humidifier further comprises a water tank and a water pump, the water pump being configured to deliver water in the water tank to the top of the water distribution cover 26 through the water feeding pipe 28.

[0103] The air conditioning device can be a humidifier, an air purifier with a humidifying function, or a water-cooled fan.

[0104] A humidifier and a wet curtain device used by the humidifier are introduced below.

[0105] The working principle of the conventional evaporative spray humidifier on the market is basically that water in the water tank at the bottom of the whole machine is transported to the top of the wet curtain assembly by a water pump, and then the water is distributed to each position of the wet curtain assembly through the top distribution structure, so as to wet the wet curtain assembly and achieve the purpose of humidification. In order to ensure that the water flow can be transported upward in the drain pipe inside the wet curtain assembly, a water feeding pipe is generally installed between the upper and lower covers of the wet curtain assembly, and the lower cover of the wet curtain assembly and the water feeding pipe are matched by soft silica gel. The other end of the soft silica gel is matched with the water inlet of the support, so as to ensure the sealing between the water feeding pipe, the lower cover of the wet curtain assembly, and the water inlet of the support by the soft and compressible characteristics of the silica gel, and ensure that the water flow can be smoothly transferred from the water inlet to the water feeding pipe in the wet curtain device without overflowing from the joint between the three, thereby causing water waste.

[0106] According to the above working principle, the following problems often occur in the actual product development and use process: the silica gel part is relatively soft and easy to deform, and the user may cause the silica gel part to deform or even displace due to improper installation method or excessive force during installation of the wet curtain device, so as to fail to ensure the good cooperation between the water feeding pipe and the through hole of the support, thereby reducing the amount of water feeding and causing the humidification amount to be unsatisfactory.

[0107] According to the above reasons, the present embodiment introduces a new design scheme of the humidifier wet curtain device to better avoid the above problems and achieve the idealization of the humidification amount.

[0108] Specific scheme:

[0109] Figure 1 The sectional view of the whole wet curtain device placed on the support is shown in FIG. 1. Figure 1 As can be seen, the wet curtain device is a whole component, and the user can replace and take the movable part and assemble it on the support according to a specific orientation to ensure that the water inlet on the support is in communication with the water feeding pipe inside the wet curtain assembly and meet the water feeding function. The wet curtain assembly mainly includes a wet curtain assembly upper cover, a wet curtain assembly water distribution cover, a wet curtain assembly spunlace fabric, a water feeding pipe, a wet curtain assembly lower cover, and a silica gel part. The specific functions of each component are described below.

[0110] Support: the bearing of the wet curtain assembly, the wet curtain assembly is placed on the support, and the support needs to be designed with a water inlet hole, which cooperates with the water inlet pipe and silica gel part inside the wet curtain assembly to meet the channel of water pump transportation.

[0111] Silica gel part: fixed on the lower cover of the wet curtain through a special assembly structure, acting as a transition between the support and the water inlet pipe.

[0112] Wet curtain lower cover: the bottom support of the entire wet curtain device, with silica gel part assembled on it.

[0113] Water inlet pipe: the installation hole inside the wet curtain device, communicating with the water inlet hole of the support.

[0114] Wet curtain assembly spunlace: the most core humidifying element in the entire wet curtain assembly.

[0115] Wet curtain assembly water distribution cover: evenly distributes the water flow transported by the water pump through the water inlet pipe to a circle of water outlet holes through reasonable structural layout and drainage scheme, realizing uniform water distribution of the entire wet curtain assembly water distribution cover.

[0116] Wet curtain assembly upper cover: the top surface of the entire wet curtain device, cooperating with the wet curtain assembly water distribution cover to form a water channel for water flow transportation.

[0117] Specifically, as shown in Figure 4 , the silica gel part has two circles of flange structures at the bottom, and the top is a relatively long cylindrical shape, and the structure of the wet curtain lower cover is as shown in Figure 3 , the bottom also has a corresponding flange structure clamped in the area between the two flanges of the silica gel part.

[0118] As shown in Figures 1 to 4 , the outer side of the silica gel part has two flanges, respectively the first flange (flange 296) and the second flange (first positioning part 292), and the inner side has only one flange (fourth convex rib 294), and the wet curtain lower cover has two flanges at the opening, respectively the first flange (first convex rib 223) and the second flange (second convex rib 224).

[0119] When the silica gel part is fitted into the designated position of the wet curtain lower cover, the assembly diagram is as shown in Figure 1As shown, one side of the first flange of the silica gel piece is placed on the first flange of the wet curtain lower cover, and the other side is flush with the outer surface of the wet curtain lower cover, serving as an appearance surface; meanwhile, the second flange of the silica gel piece is clamped in the middle by the two flanges of the wet curtain lower cover. When the user installs the wet curtain device, the upper water hole of the support will extrude the first flange of the silica gel outer ring to deform, and the first flange will deform to compress the second flange of the silica gel piece to deform when the upper water hole is not accurately positioned from top to bottom. Since the two sides of the second flange are blocked by the flanges of the wet curtain lower cover, the deformation of the silica gel piece is inhibited; thereby ensuring that the upper water hole can pass through the large round corner (guide chamfer 298) at the bottom of the silica gel piece to guide it to perfectly transition to the inner ring of the silica gel piece.

[0120] The inner ring of the silica gel piece has a flange (fourth protruding rib 294), the upper part of which is in contact with the water inlet pipe, and the lower end is in contact with the top of the upper water hole of the wet curtain assembly, and the two extrude the silica gel piece at the flange, ensuring good conduction of the mounting hole.

[0121] Meanwhile, since the tail of the silica gel piece is long and easy to deform, the second flange (second protruding rib 224) of the wet curtain lower cover is designed to be relatively high in size, and a circle is in contact with the tail end of the silica gel piece, ensuring that the tail end of the silica gel piece will not be tilted and deformed when the upper water hole of the support and the water inlet pipe are extruded, thereby further ensuring good conduction of the mounting hole.

[0122] The technical effect of the embodiment is that the reasonable silica gel piece fixing scheme ensures that the wet curtain device cannot be normally used due to user's misoperation, and better ensures the reliability of the product.

[0123] In the description of the present specification, the terms "connection", "installation", "fixation" and the like should be understood in a broad sense, for example, "connection" can be fixed connection, or detachable connection, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium.
